molecule, [alpha] changes during the course of the vibration
And the total energy ([E.sub.tot]) for an N molecule diatomic
gas becomes 
Therein appear speed c of light in vacuo, R that would represent the instantaneous internuclear separation of a diatomic
molecule, equilibrium internuclear distance [R.sub.e] and energy h c [D.sub.e] at the dissociation limit relative to the energy for R = [R.sub.e].
In the Born-Oppenheimer approximation, the vibration-rotation motion of a diatomic
molecule is described by the wave function [[PSI].sub.vJ] and the energy [E.sub.vJ] that are, respectively, the eigenfunction and the eigenvalue of the radial Schrodinger equation

molecules," Journal of Molecular Spectroscopy, vol.
All heteronuclear diatomic
molecules are polar, single or multiple bonds are formed between the A and B atoms, the dipole moment of the AB molecule is related to the polar character of the bonding, the dipole moment of the bond itself is the molecular dipole moment.
Domoic acid (DA) is primarily produced by marine diatomic
algae of the genus Pseudo-nitzschia (Perl et al.
Herzberg, "Rotation-Vibration spectra of diatomic
and simple polyatomic molecules with long absorbing paths.
Nitrogen, despite being a simple diatomic
molecule, has quite complex plasma chemistry and kinetics, especially in mixtures with oxygen [15,16].
CO has been classified with other biologically active diatomic
molecules, such as nitrogen oxide (NO) and hydrogen sulphide (H2S), as a gasotransmitter .
For thirty years Mayer has been investigating the quantum mechanical meaning of the bond order, the actual valence of an atom in a molecule, and the different atomic and diatomic
energy components reflecting the energetics of molecule formation.
In the microcomponent study of organic compounds, the chemical structure and variation characteristics of the corresponding macromolecules (except for paramagnetic diatomic
molecules) may be determined according to the distribution of the characteristic spectrum and fingerprint region absorption peak in the spectrum.
