Time-resolved resonance Raman spectra are obtained for the lowest excited triplet state T, and the radical cation of 5-dibenzosuberenol (DBCH-5-01). It is concluded, based on the large downshifts of the Raman bands assignable to the C=C stretch of the central ring, that the C=C bond is weakened mark
