✦ Synopsis

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 observed change in pokrizability, 2.2 A', is compared with values found from solvent shift work and n-electron calculations. bad It is well known that elect I perturbations may be applied to the electronic transitions of molecules in order to determine excited state dipole momen ts, poiarizabilities and related properties. This is possible even in solutions under conditions of relatively low resolution. Examples of recent work [l-3] are typical in that a polar solute molecule is used. In

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.
