Harmonic Franck—Condon Overlap Integrals Including Displacement of Normal Coordinates

One-dimensional harmonic Franck-Condon overlap integrals including a change of geometry in the electronic transition were evaluated in terms of two dimensionless parameters for quantum numbers v\\ v\ from 0 to 10. Tables of these integrals, correct to five significant figures, are available from the authors. Two recursion relationships were developed which greatly reduced computing time. The physical quantities required to find an integral in the tables are the ground and excited state vibrational frequencies and the displacement of ground and excited state normal coordinates.
