An inversion method is presented for diatomic potential curves of electronically excited states which are the intermediate states for continuum resonance Raman scattering processes. Assuming a parametric form of the potential, the parameters are directly given as a function of certain frequencies which can be taken from experimentally determined Raman profiles. The origin of the procedure is a reflection principle which states that the nodal structure of vibrational wavefunctions serving as initial or final states in the two‐photon process is apparent in the Raman cross‐section recorded as a function of excitation frequency. The Cl 2 molecule is used as an illustrative example. © 1997 John Wiley & Sons, Ltd.
