The transition linewidth AE in crystal C I' 6 J6, C6D6 and symC6H3D3 has been measured as a function of temperature T from 4.2 to 135"K, and it extrapolates to a common value of tie = 50 cm-' at 0°K. In CbH6 aE = (50+ 7T"2) cm-', indicative of strong cxciton-phonon couplin g, and there is a line shi

✦ Synopsis
The benzene *Ezu -+ !A L,z emission spectrum is observed in a flowing argon after,olow produced by a low power microwave discharge. Flo emission of dissociation products was found in the 2000-7000 X region.

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.
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
