Spectra of diatomic molecules
Clearly N is perpendicular to R, so the projection of J onto R is the same as the projection LR with eigenvalue ¤1 h of L. (We now reserve z for a direction ̄xed in space, and use the subscript R for a component along R). Because total angular moment of an isolated molecule is constant, eigenfunctions of H when L is non-zero will have the quantum numbers J , MJ , ¤, s (to describe the electronic...
متن کاملAnharmonic Algebraic Model of Thermodynamic Properties of Diatomic Molecules
An algebraic model based on Lie-algebraic techniques is applied to the analysis of thermodynamic vibrational properties of diatomic molecules. The local anharmonic effects are described by a Morse-like potential and corresponding anharmonic bosons associated with the U(2) algebra. A vibrational high temperature partition function and the related thermodynamic functions are derived in terms of t...

An algebraic model based on Lie-algebraic and discrete symmetry techniques is applied to the analysis of thermodynamic vibrational properties of molecules. The local anharmonic effects are described by a Morse-like potential and the corresponding anharmonic bosons are associated with the SU(2) algebra.

متن کاملLuminescence of Diatomic Molecules
Photoionization has been used to produce ions of N2 , 0 2 . and CO in definite excited states. Deactivating collisions of these ions with molecular gases were described in paper I, where the cross sections of ions with thermal velocity are given for various electronic and vibrational states. By application of an electric field the charged particles are accelerated yielding information on the in...
متن کاملStructure of diatomic molecules
Molecules are of course atoms that are held together by shared valence electrons. That is, most of each atom is pretty much as it would be if the atom were isolated, but one or a few electrons are located in regions (for example, between two atomic cores) where they lead to an overall attractive e®ect. To see roughly how this works, you might consider the case of two protons and two electrons a...
