One‐color two‐photon zero kinetic energy (ZEKE)‐spectra of CH3I were obtained via an intermediate resonant state. In contrast to one‐photon spectra an intense progression in the totally symmetric C–I stretching mode ν3+ is observed. The observation can be explained by a resonant‐Raman like enhancement in the intermediate dissociative state.
