Franck–Condon Factors and R–Centroids of Some Molecular Transitions of Sio and Baf Molecules

Abstract

Franck–Condon factors and r-centroids were computed for some molecular transitions of
SiO and BaF molecules using molecular constants and Hua potential depending on theoretical
calculations, also plotting the potential energy curves of ground state for these molecules and
we got to high value of potential in minimum value of bond length. So minimum value of
potential that in bond length equal to bond length at equilibrium distance and after that when
bond length reach to highest values, that lead to dissociation in these bonds and as result of that
the molecule be stable.
