Etude comparée des constantes moléculaires de HBr et de DBr : Application à la détermination des constantes moléculaires de TBr

Abstract

In this paper, the adiabatic and non-adiabatic corrections to the Born–Oppenheimer approximation are numerically determined for Dunham's equilibrium constants Y10 and Y01 of H Br and DBr molecules.In the case of the Y20, Y11, and Y02 constants, only the adiabatic corrections are significant.The correct isotopic relations using these corrections allow the TBr equilibrium constants calculation from the HBr and DBr ones.
