molecule

 [mol´ĕ-kūl]
a group of atoms joined by chemical bonds; the smallest amount of a substance that possesses its characteristic properties.
adhesion m's (cell adhesion m's (CAM)) cell surface glycoproteins that mediate intercell adhesion in vertebrates.
middle molecule any molecule that has an atomic mass between 350 and 2000 daltons; these accumulate in the body fluids of patients with uremia.

mol·e·cule

(mol'ĕ-kyūl),
The smallest possible quantity of a di-, tri-, or polyatomic substance that retains the chemical properties of the substance.
[Mod. L. molecula, dim. of L. moles, mass]

molecule

The smallest unit of a substance that can exist alone and retain its core chemical and physical characteristics.

trivial name

A popular, working, or common name for a thing or process that has a formal name. See CD, DSM-IV, EC, SI.
Trivial name
Disease–eg, Lou Gehrig's disease for amyotrophic lateral sclerosis
Molecule–eg, Teflon for polytetrafluoroethylene
Organ–eg, anterior pituitary for adenohypophysis
Structure–eg, vocal cord for vocal fold–plica vocalis, or fallopian tube for tuba uterina, which is not standard nomenclature or based on 'official' rules delineated by international agencies or organizations–eg, American Psychiatric Association, Enzyme Commission, the International System, Terminologia Anatomica, etc

The second goal of this project is, therefore, developing and implementing both exact and approximate computationally efficient quantum dynamics methods applicable to polyatomic molecules. The last goal of the project is developing systematic methods for interpreting spectra of complex systems in terms of the underlying nuclear and electronic dynamics.
Some of the potential models have been identified in order to describe the interactions in the nuclei and nuclei-particle and structures of the diatomic and polyatomic molecules. Some of these potentials are called as follows: the Kratzer, Morse, Eckart, Rosen-Morse, Manning-Rosen, Poschl-Teller, Hulthen, WoodsSaxon, Scarf, Schioberg, Deng-Fan, and Cusp potentials [1-13].

Their topics include the method of least squares, determining the rotational constants by the spectroscopy of polyatomic molecules, determining equilibrium structures and potential energy functions for diatomic molecules, and structures averages over nuclear motions.
Seven studies consider such aspects as highly excited valence states of polyatomic molecules, proton transfer reactions in excited states, protonucleophilic substitution reactions, photo-animation with ammonia and amines, and the DNA-templated assembly of helical multi-chromophore aggregates.
The local mode picture gives new insight into the highly-excited vibrational motion of polyatomic molecules. Don Irish, FCIC, also studies molecular vibrations but uses Roman light scattering rather than inflated absorption.
They will also completely change the way ellipticity is considered in attosecond science and have an impact far beyond the study of chiral compounds, opening new perspectives for the resolution of the fastest dynamics occurring in polyatomic molecules and solid state physics.
