The importance of kinematic perturbations on the two-photon spectrum of benzene corresponding to the 'Bz, 6 'A,, transition is demonstrated by the spectrum of s-benzene-d3 iy in S-C6H3D3-pg, absent in the C&e spectrum (where it is ezg) appears strong-

β¦ Synopsis
The two-photon absorption spectra at -1 cm-' resolution is presented for benzene46 and benzenedb.
A number ofvibrations of bt,, bzu. etu and czu symmetry are assigned and the results compared with theoretical espectations. It appears as if the n-rlectron states dominate the coupling to the radiation in causing the two-photon transitions.

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.
We perform multiconfiguration quadratic response theory calculations of vibronically induced symmetry and parity forbidden 'A,k-'B2,, two-photon transitionsofbenzene. The followingorder ofvibronic activity is found; Y,.,> Y,~> Y,~z= Y,~> Y!,> Y,\*> Y?,,. The two-photon activity is crucially dependen
