β¦ Synopsis
Evidence for vibronic coupling involving as vibrations has been found in system I of the one-photon spectrum of anthracene. A model for b,, coupling between the low-energy electronic states can account for the magnitudes of both the pre-resonance Raman scattering and the transition dipole length induced into system I of the one-photon spectrum.

The lower&y absorption system of dibenzofuran vapour has been re-measured at high resolution. The origin band (0) and the prominent band at 0 + 445 have different contours, and so have opposite polarization. In the solid state, the frequency of the prominent vibrational interval is already known to
