Molecular mechanics simulations, for example, use a single classical expression for the energy of a compound, for instance the harmonic oscillator.

Molecular dynamics ( MD ) use either quantum mechanics, Newton's laws of motion or a mixed model to examine the time-dependent behavior of systems, including vibrations or Brownian motion and reactions.

; Molecular modelling: Methods for modelling molecular structures without necessarily referring to quantum mechanics.

; Molecular dynamics: Application of classical mechanics for simulating the movement of the nuclei of an assembly of atoms and molecules.

; Molecular mechanics: Modelling of the intra-and inter-molecular interaction potential energy surfaces via a sum of interaction forces.

Molecular biophysicists often consider complex biological events as systems of interacting units which can be understood through statistical mechanics, thermodynamics and chemical kinetics.

* Molecular mechanics

Molecular mechanics can be used to study small molecules as well as large biological systems or material assemblies with many thousands to millions of atoms.

Molecular mechanics potential energy function with continuum solvent.

The Quantized Valence Bonds ' Molecular Mechanics ( QVBMM ) force field ( implemented in Exorga, Incorporated's StruMM3D product, once named STR3DI32 ) is unique in molecular mechanics as the only one to directly use all lone pair interactions in all of its energy calculations.

Molecular mechanics potential energy functions have been used to calculate binding constants, protein folding kinetics, protonation equilibria, active site coordinates, and to design binding sites.

Molecular mechanics or molecular dynamics are most often used to predict the conformation of the small molecule and to model conformational changes in the biological target that may occur when the small molecule binds to it.

Molecular mechanics methods may also be used to provide semi-quantitative prediction of the binding affinity.

* Molecular mechanics.

This may include treating atoms as the smallest individual unit ( the Molecular mechanics approach ), or explicitly modeling electrons of each atom ( the quantum chemistry approach ).

Molecular mechanics is one aspect of molecular modelling, as it refers to the use of classical mechanics / Newtonian mechanics to describe the physical basis behind the models.

* Molecular mechanics

In the case of quantum mechanics, the main part of the three-body problem refers to the finding the eigenstates and their energies .. For a special case of the quantum three-body problem known as the Hydrogen Molecular ion, the eigenenergies are solvable analytically ( see discussion in quantum mechanical version of Euler's three-body problem ) in terms a generalization of the Lambert W function.

* Molecular mechanics

Molecular scale electronics, also called single molecule electronics, is a branch of nanotechnology that uses single molecules, or nanoscale collections of single molecules, as electronic components.

Molecular phylogeny uses such data to build a " relationship tree " that shows the probable evolution of various organisms.

Molecular biology research uses numerous proteins and enzymes many of which are from expression systems ; particularly DNA polymerase for PCR, reverse transcriptase for RNA analysis and restriction endonucleases for cloning.

Molecular orbital ( MO ) theory uses a linear combination of atomic orbitals ( LCAO ) to represent molecular orbitals involving the whole molecule.

TRIUMF uses subatomic particles as probes of materials structure at the Centre for Molecular and Materials Science ( CMMS ).

* Molecular model, a physicochemical or mathematical description that models the behaviour of molecules

* Molecular model

* Molecular replacement – if a related structure is known, it can be used as a search model in molecular replacement to determine the orientation and position of the molecules within the unit cell.

NAMD ( Not ( just ) Another Molecular Dynamics program ) is a free-of-charge molecular dynamics simulation package written using the Charm ++ parallel programming model, noted for its parallel efficiency and often used to simulate large systems ( millions of atoms ).

He established the roundworm Caenorhabditis elegans as a model organism for the investigation of developmental biology, and founded the Molecular Sciences Institute in Berkeley, California, U. S ..

All were impressed by the new DNA model, especially Brenner who subsequently worked with Crick at Cambridge in the Cavendish Laboratory and the new Laboratory of Molecular Biology.

Molecular modeling encompasses all theoretical methods and computational techniques used to model or mimic the behaviour of molecules.

Molecular orbital theory is another model for understanding how atoms and electrons are assembled into molecules and polyatomic ions.

* The male model featured in a newspaper advertisement promoting the Food Science course published in 2005 was a student of module group MB0403 from the Molecular Biotechnology course.

The article " Über die von der molekularkinetischen Theorie der Wärme geforderte Bewegung von in ruhenden Flüssigkeiten suspendierten Teilchen " (" On the Motion of Small Particles Suspended in a Stationary Liquid, as Required by the Molecular Kinetic Theory of Heat "), received May 11 and published July 18, delineated a stochastic model of Brownian motion.

However, Watson and Crick found Fraser's model to be too ill-defined to comment specifically on its inadequacies in their publication in " Nature " ( 1953 ): Molecular Structure of Nucleic Acids.
