Multidimensional Franck–Condon integrals and Duschinsky mixing effects

Abstract: A general method for calculating multidimensional Franck–Condon integrals for polyatomic molecules is given. These integrals are derived by means of a multivariable generating function which incorporates both the transformation of the normal mode coordinates between initial and final electronic states and their frequency changes. The normal mode transformation or mode mixing (Duschinsky effect) scrambles the occupations of the normal modes, leading to unusual distributions, which at certain values of the angle… Show more

“…[32][33][34][35][36][37] This algorithm is an extension of the one previously reported by our group for a = 0, which could handle vibronic expansions comprised of >10 9 terms. In general, the Franck-Condon overlap integrals, s a,m , are only difficult to determine when the w and w represent different normal coordinate systems with different origins and orientations.…”

In Appendix B, we provide a derivation of the analytic expressions for the recursion relations and discuss their implementation for the hot band case a j = 1, a k = 0, k =j, required here.…”
