The change in the in-plane polxizability of benzene uPon excitation from the 'Atg state to the 'Bzu state is deduced from electric field perturbation experiments. These are carried out on the First vibronically allowed band of benzene in a rigid solution of 3.methylpentane (3.XIP) at 7?K. The obser

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.
