Hyperfine Structure Constants for Diatomic Molecules
The multiconfiguration valence-bond method (VB) is applied to diatomic molecules using the Hartree-Fock (HF) atomic basis set. The hyperfine constant, Fermi contact term, is computed as a function of the interatomic separation for the X2∏ ground state of 17OH and X1∑ ground state of 107AgH+ molecules. This study leads to a number of conclusions about the influence of correlation and polarizatio...
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...
متن کاملSecond-order effects on the hyperfine structure of P states of alkali-metal atoms
We analyze second-order M1-M1 and M1-E2 effects on the hyperfine structure HFS of the lowest-energy P states of alkali-metal atoms arising from the coupling of the two J=1 /2,3 /2 fine-structure levels through the hyperfine interaction. We find these effects to be especially sizable in Li, leading to a 9 correction to the most accurate reported experimental value of the A P1/2 HFS constant of L...
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 کاملSpectra 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...
