In a previous article [Chem. Phys. 1994, 186, 355-374], Ruhoff derived a set of recursion relations for calculating multidimensional Franck-Condon overlap integrals within the harmonic approximation, taking into account the Duschinsky mixing effect. We show here how these relations can be implemented in a computationally efficient manner.
