More complex molecules have many bonds, and their vibrational spectra are correspondingly more complex, i. e. big molecules have many peaks in their IR spectra.

A monochromator's adjustment range might cover the visible spectrum and some part of both or either of the nearby ultraviolet ( UV ) and infrared ( IR ) spectra, although monochromators are built for a great variety of optical ranges, and to a great many designs.

Today, IR spectra are used in thousands of laboratories around the globe by scientists in many fields.

By DFT and TDDFT methods one can obtain IR, Raman and UV spectra.

The molecular overtone and combination bands seen in the near IR are typically very broad, leading to a complex spectra ; it can be difficult to assign specific features to specific chemical components.

These compounds were used to study the kinetics of tetrahedral intermediate decomposition into its respective carbonyl species, and to measure the IR, UV, and NMR spectra of the tetrahedral adduct.

Platelets produce sharp absorption peaks at 1359 – 1375 and 330 cm < sup >− 1 </ sup > in IR absorption spectra ; remarkably, the position of the first peak depends on the platelet size.

* Simple spectra predictions, including 13C-NMR, 1H-NMR ( based on additive rules and functional group lookup methods ), and IR

* Various molecular properties: IR, Raman, VCD, UV, XAS spectra ; NMR and EPR ( ESR ) parameters.

Lowry resigned from the Cabinet after it was revealed at the Moriarty Tribunal that businessman Ben Dunne had paid for an IR £ 395, 000 extension to Lowry's Tipperary home.

Because it is warm, the surface radiates far IR thermal radiation that consists of wavelengths that are predominantly much longer than the wavelengths that were absorbed ( the overlap between the incident solar spectrum and the terrestrial thermal spectrum is small enough to be neglected for most purposes ).

That same year, Kent and colleagues published a paper in American Documentation describing the precision and recall measures as well as detailing a proposed " framework " for evaluating an IR system which included statistical sampling methods for determining the number of relevant documents not retrieved.

In order for a vibrational mode in a molecule to be " IR active ," it must be associated with changes in the dipole.

The second ( more recent and more advanced ) technique employs focal plane array detection for infrared chemical imaging, where the image contrast is determined by the response of individual sample regions to particular IR wavelengths selected by the user.

There are some materials like indium tin oxide ( ITO ) that are metallic conductors ( actually degenerate semiconductors ) for which this threshold is in the infrared, which is why they are transparent in the visible, but good mirrors in the IR.

It is a separate field within computer science ( closer to databases ), but IR relies on some NLP methods ( for example, stemming ).

* IR patch, a specialized patch for military Combat Identification.

These kits included IR capability, a new plastic memory door to accommodate the IR diodes, a memory card with 1 MB, the new ROM for Palm OS 2. 0, and a CD ROM with updated desktop software.

A third kind of wireless device for people with hearing loss is the infra red ( IR ) system, which also requires a receiver to be worn by the listener.

Usually the emitter for the IR device, that is, the component that sends out the signal, uses an AC adaptor.

The advantage of the IR wireless system is that people in adjoining rooms cannot listen in on conversations, making it useful for situations where privacy and confidentiality are required.

# Weight gain, fat storage, difficulty losing weight – for most people, excess weight is from high fat storage ; the fat in IR is generally stored in and around abdominal organs in both males and females.

Since insulin is the primary hormonal signal for energy storage into fat cells, which tend to retain their sensitivity in the face of hepatic and skeletal muscle resistance, IR stimulates the formation of new fatty tissue and accelerates weight gain.

Moreover, most organic compounds absorb and emit light in the infrared ( IR ) so, for example, the recent detection of methane in the atmosphere of Mars was achieved using an IR ground-based telescope, NASA's 3-meter Infrared Telescope Facility atop Mauna Kea, Hawaii.

** Specifications for IR over optical fiber or a wireless IR communication link

Aspects of international relations have been studied for thousands of years, since the time of Thucydides, but IR became a separate and definable discipline in the early 20th century.

IR ( International Relations ) is an orkut community, originally designed for people interested in international relations in different countries to interact.

The upper section also contains a separate missile tracking system that is slaved to the operator's optics, based on a television camera optimized for the IR band.

If operation is required where no line of sight is possible, for instance when controlling equipment in another room or installed in a cabinet, many brands of IR extenders are available for this on the market.

This dependence on the polarizability differs from Infrared spectroscopy where the interaction between the molecule and light is determined by the dipole moment ; this contrasting feature allows to analyze transitions that might not be IR active via Raman spectroscopy, as exemplified by the rule of mutual exclusion in centrosymmetric molecules.

Anarchy in this view is constituted by state interaction, rather than accepted as a natural and immutable feature of international life as viewed by neo-realist IR scholars.

A unique feature of the HETE mission was its capability to localize GRBs with ~ 10 arc second accuracy in near real time aboard the spacecraft, and to transmit these positions directly to a network of receivers at existing ground-based observatories enabling rapid, sensitive follow-up studies in the radio, IR, and optical bands.

ARMIGER was to feature an IR seeker, accurate Inertial Measurement Unit ( INS ) for navigational purposes, long range, high supersonic speed, reliability, and direct hit capability.

The B center has a characteristic IR absorption spectrum ( see the infrared absorption picture above ) with a sharp peak at 1332 cm < sup >− 1 </ sup > and a broader feature at 1280 cm < sup >− 1 </ sup >.

They observed intense absorptions in the IR bands at 3300 and 3210 cm < sup >− 1 </ sup > for a solution of ( CH < sub > 3 </ sub >)< sub > 2 </ sub > NHBH < sub > 3 </ sub >.

By applying intense tunable IR lasers, like IR-OPOs or IR free electron lasers, the wavelength dependence of the IRMPD yield can be studied.

The latter has a characteristic IR absorption spectrum with a sharp peak at 1332 cm < sup >− 1 </ sup > and broader and weaker peaks at 1115, 1046 and 950 cm < sup >− 1 </ sup >.

The A center shows an IR absorption spectrum with no sharp features, which is distinctly different from that of the C or B centers.

If the molecule is symmetrical, e. g. N < sub > 2 </ sub >, the band is not observed in the IR spectrum, but only in the Raman spectrum.

The ν < sub > SH </ sub > band appears near 2400 cm < sup >− 1 </ sup > in the IR spectrum.

* It uses RF ( 27 MHz R / C band ) instead of IR for communication.

The missile's seeker is reported to use dual band technology array similar to that of US FIM-92 Stinger ( infrared and ultraviolet ), with IRCCM ( IR ECCM ) ability to reduce background IR radiation to reduce the effectiveness of enemy flares.

These materials have exhibited near theoretical transmission in the 3 – 5 μm IR band.

The common plastic poly ( methyl methacrylate ) ( PMMA ) absorbs IR light in the 2. 8 – 25 µm wavelength band, so CO < sub > 2 </ sub > lasers have been used in recent years for fabricating microfluidic devices from it, with channel widths of a few hundred micrometers.
