Nuclear magnetic resonance ( NMR ) is a technique by which external magnetic fields can be used to find resonance modes of individual electrons, thus giving information about the atomic, molecular and bond structure of their neighborhood.

As in the case of the isoelectronic nitrate ion, the symmetry can be achieved by a resonance between three structures:

This resonance can be summarized by a model with fractional bonds and delocalized charges:

* FRET Fluorescence resonance energy transfer is used to study protein interactions, detect specific nucleic acid sequences and used as biosensors, while fluorescence lifetime ( FLIM ) can give an additional layer of information.

The Q factor of an inductor can be found through the following formula, where R is its internal ( Series Model ) electrical resistance and is the inductive reactance at resonance:

In a 1971 paper in the journal Science, Dr. Raymond Damadian, an Armenian-American physician, scientist, and professor at the Downstate Medical Center State University of New York ( SUNY ), reported that tumors and normal tissue can be distinguished in vivo by nuclear magnetic resonance (" NMR ").

Quintessence can have distinctive characteristics, called resonance, which are broken down into three categories: dynamic, static, and entropic.

At the surface of a metal resonance effects known as surface plasmons can result.

This increase in fluid can be visualized using magnetic resonance neurography, and thus MR neurography can identify nerve irritation and / or injury.

Like the isoelectronic carbonate ion, the nitrate ion can be represented by resonance structures:

Quantum dots ( nanoparticles with quantum confinement properties, such as size-tunable light emission ), when used in conjunction with MRI ( magnetic resonance imaging ), can produce exceptional images of tumor sites.

Under some circumstances, a resonant system can be stable and self-correcting, so that the bodies remain in resonance.

* the point of conjunction can oscillate ( librate ) around an equilibrium point defined by the resonance.

* given non-zero eccentricities, the nodes or periapsides can drift ( a resonance related, short period, not secular precession ).

Carbanions can be stabilized by resonance ( as in the case of the aromatic cyclopentadienyl anion ) or by the presence of electron-withdrawing substituents ( as in the case of the triphenylmethyl anion ).

The partial double bond character can be strengthened or weakened by modifications that favor one resonance form over another.

Molecular spectra can be obtained due to electron spin states ( electron paramagnetic resonance ), molecular rotations, molecular vibration and electronic states.

showed that we can use macroscopic oil droplets on a vibrating surface as a model of wave – particle duality — localized droplet creates periodical waves around and interaction with them leads to quantum-like phenomena: interference in double-slit experiment, unpredictable tunneling ( depending in complicated way on practically hidden state of field ) and orbit quantization ( that particle has to ' find a resonance ' with field perturbations it creates — after one orbit, its internal phase has to return to the initial state ).

This effect can be much deeper, however, causing a vibration of the soul or an " inner resonance "— a spiritual effect in which the colour touches the soul itself.

A quartz crystal can be modelled as an electrical network with a low impedance ( series ) and a high impedance ( parallel ) resonance point spaced closely together.

The output frequency of a quartz oscillator can be either the fundamental resonance or a multiple of the resonance, called an overtone frequency.

The maximum Q for a high stability quartz oscillator can be estimated as Q = 1. 6 × 10 < sup > 7 </ sup >/ f, where f is the resonance frequency in megahertz.

The data reported here are either from spectra from which the adsorbed water resonance could easily be eliminated or from spectra of samples evacuated and sealed off at 375-degrees-C which contain no adsorbed water.

A clerk in the outer office took him in to Sheriff Carruthers, a big, paunchy man with thick, white hair and a voice with a senatorial resonance which suggested he should be running for higher office.

Also, this study was the first Functional magnetic resonance imaging ( fMRI ) study to be done involving GC's and more research is necessary to support these findings.

The emitted radiation may also be of the same wavelength as the absorbed radiation, termed " resonance fluorescence ".

Under certain conditions – for instance resonance or strong spanwise correlation of the lift force – the resulting motion of the structure due to the lift fluctuations may be strongly enhanced.

In this story, the coldest place concerned is the dark side of Mercury, which at the time the story was written was thought to be tidally locked with the Sun ( it was found to rotate in a 2: 3 resonance after Niven received payment for the story, but before it was published ).

This electromagnetic field has just the right frequency, known as the resonance frequency, to be absorbed and flip the spin of the protons in the magnetic field.

Unfortunately, as soon as cyclotron resonance became available and the shape of the balloon could be determined, it was found that the assumption that the balloon was spherical did not hold at all, except perhaps in the case of caesium.

The periods of the Moon's orbit around the Earth and the Earth's orbit around the Sun are believed to be independent, and appear to have no known physical resonance.

* Angiography or Magnetic resonance imaging angiography when the blood vessels might be affected

Except as noted in the Laplace resonance figure ( below ), a resonance ratio in this article should be interpreted as the ratio of number of orbits completed in the same time interval, rather than as the ratio of orbital periods ( which would be the inverse ratio ).

This resonance applies only to bodies on highly inclined orbits ; as a consequence, such orbits tend to be unstable, since the growing eccentricity would result in small pericenters, typically leading to a collision or ( for large moons ) destruction by tidal forces.

Additionally, Haumea is believed to be in a 7: 12 resonance with Neptune, and Eris and Makemake may be in 5: 17 and 6: 11 resonances with Neptune, respectively.

Though strictly not musical, the Muslim call to prayer ( azan ) is always chanted by tenors, possibly due to the highly placed resonance of the tenor voice which allows it to be heard from a longer distance than baritones or basses during pre-amplification times.

Since this circuit lacked any frequency-selective elements besides the broad resonance of the antenna, it had little ability to reject unwanted stations, so all stations within a wide band of frequencies were heard in the earphone ( in practice the most powerful usually drowns out the others ).

The resonance is most often heard when the fundamental frequency of the string is in unison or an octave lower or higher than the catalyst note, although it can occur for other intervals, such as a fifth, with less effect.

A functional magnetic resonance imaging ( fMRI ) study found that minimally conscious state patients showed activation in auditory networks when they heard narratives that had personally meaningful content that were read forwards by a familiar voice.

The first diatomic hydride investigated by the paramagnetic resonance method was the OH radical.

The timbre remains that of the instruments unclouded by resonance.

The magnetic resonance absorption was detected by employing a Varian model Af broad line spectrometer and the associated 12-inch electromagnet system.

One sample, which had been exposed to the atmosphere after evacuation at 375-degrees-C, showed the presence of adsorbed water ( about 0.3 wt ) ) as evidenced by a weak resonance line which was very narrow at room temperature and which disappeared, due to broadening, at low temperature.

During these activities, the researchers took functional magnetic resonance imaging ( fMRI ) scans of the participants ' brains and were " surprised by the results ".

This equivalency is well explained by resonance forms.

It is estimated that acetamide is described by resonance structure A for 62 % and by B for 28 %

Also, mass spectrometry is categorized by approaches of mass analyzers: magnetic-sector, quadrupole mass analyzer, quadrupole ion trap, time-of-flight, Fourier transform ion cyclotron resonance, and so on.

As a pyramidal bond geometry is forced upon the nitrogen atom by the ring strain, the resonance of the amid bond is reduced, and the carbonyl becomes more ketone-like.

The energy of the incident photons is absorbed by the pigments and funneled to the reaction centre of this complex through resonance energy transfer.

The function of the vast majority of chlorophyll ( up to several hundred molecules per photosystem ) is to absorb light and transfer that light energy by resonance energy transfer to a specific chlorophyll pair in the reaction center of the photosystems.

* Magnetic resonance imaging ( MRI ) MRI is a method of imaging objects that uses a strong magnetic field to detect the relaxation of protons that have been perturbed by a radio-frequency pulse.

A classical Kuiper belt object, also called a cubewano ( " QB1-o ") is a low-eccentricity Kuiper belt object ( KBO ) that orbits beyond Neptune and is not controlled by an orbital resonance with Neptune.

Most cubewanos are found between the 2: 3 orbital resonance with Neptune ( populated by plutinos ) and the 1: 2 resonance.

Their semi-major axes show a preference for the middle of the main belt ; arguably, smaller objects close to the limiting resonances have been either captured into resonance or have their orbits modified by Neptune.

Io, unusually, is heated by solid flexing due to the tidal influence of Jupiter and Io's orbital resonance with neighboring large moons Europa and Ganymede, which keeps its orbit slightly eccentric.

Bracing not only strengthens the top against potential collapse due to the stress exerted by the tensioned strings, but also affects the resonance characteristics of the top.

Air inside the body vibrates as the guitar top and body is vibrated by the strings, and the response of the air cavity at different frequencies is characterized, like the rest of the guitar body, by a number of resonance modes at which it responds more strongly.
