Abstract Franck–Condon overlaps are described as the matrix elements of unitary operators related to the spatial displacement and the frequency shift. They are calculated exactly by means of the coherent state representation. Furthermore, the generalized matrix elements of xj, e−αx, and e−βx2 between two states with different equilibrium coordinates and frequency are evaluated in the same way.
