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 radiatio

The electric field induced shift of the clcctronic origin of the lowest B,, singlet state of tetracene and pentacene in p-terphenyl at 1.8"K has been measured. From this shift we calculate the difference in polarizability of this state and the ground state along the long molecular nsis to be 4.5 ? 0
