mol·e·cule

 (mŏl′ĭ-kyo͞ol′)
n.
1. The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces.
2. A small particle; a tiny bit.

mol•e•cule

(ˈmɒl əˌkyul)

n.
1. the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
2. a quantity of a substance, the weight of which is numerically equal to the molecular weight; gram molecule.
3. any very small particle.

mol·e·cule

(mŏl′ĭ-kyo͞ol′)
A group of two or more atoms linked together by sharing electrons in a chemical bond.

molecule

The smallest part of an element or chemical compound which can exist independently with all the properties of the element or compound. It is made up of one or more atoms bonded together in a fixed whole number ratio.

The fourth goal is to achieve an accurate quantum dynamical description of the reaction of hydrogen containing polyatomic molecules at surfaces at incidence energies of catalytic interest (in the quantum regime).
Among the topics are numerical methods, measuring absolute cross sections of electron scattering by isolated molecules, applying nonlocal resonance theory to diatomic molecules, and vibrational excitations of polyatomic molecules.
Contributors describe their work in integral equation theories (including bridge functions and applications to classical fluids), the chemical environment of ionic liquids (including the links between liquid structure, dynamics and solvation), counter-ion condensation in nucleic acids, physiochemical applications of scanning electrochemical microscopy, certain shapes of centrosymmetric cyclic dimers involving weak hydrogen bonds, and time-resolved photoelectron spectroscopy of nonadiabatic dynamics in polyatomic molecules.
