Rotational perturbations are identified in Doppler-free two-photon spectra of the 14' 9 and 14r 0 1' 9 vibronic bands in ChH6. Evidence is found that Coriolis coupling between some of the rotational levels of two distinct vibrational states within St is the mechanism responsible. Thin coupling mecha

The three-photon spectrum of the 'Bzu-l Alg transition in gas-phase benzene has been recorded and analyzed. Though formally allowed at the three-photon level, this transition is seen to be entirely vibronically induced. The last unknown e2g vibration (vg) in the 'Bzu state is identified.
