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 [18]
CO has been classified with other biologically active diatomic molecules, such as nitrogen oxide (NO) and hydrogen sulphide (H2S), as a gasotransmitter [1].
Moist air is a mixture of air (itself composed primarily of diatomic molecules, notably [N.sub.2] and [O.sub.2]) and water vapor ([H.sub.2]O).
The basic model of our study considers a diatomic molecule immersed in an atomic solvent as a quantum rotor (small system S) coupled with the translational degrees of freedom of both the diatomic and the solvent (the bath B) by means of the anisotropic potential [6]
In conclusions, we have investigated the classical limit in the photo-detachment of homo-nuclear diatomic negative ion using two-center-model calculations and by simply equating probability densities from two coherent sources to the probability density from the diatomic molecule negative ion.

Following the pioneering work of Burrau [20] and Wilson [22,22], Teller recognised that the amplitude functions from the solution of Schroedinger's equation in ellipsoidal coordinates to treat interatomic interactions in a diatomic molecule were applicable also to the hydrogen atom itself [23].
Weidemuller's group created molecules made of an atom of lithium and one of cesium, similar to Ye's diatomic molecule of potassium and rubidium.
Two colliding atoms can absorb a photon and be photo-associated into an excited, diatomic molecule. NIST researchers investigated the fundamental rate at which this process can take place in a Bose-Einstein condensate (BEC) and demonstrated that simple classical saturation arguments do not work when applied to this situation.
