Abstract:The observation of time resolved resonance CARS spectra of fluorene-h10 and -d10 in their T1 states in room temperature solution are reported. Observed Raman frequencies are assigned on the basis of a crude normal coordinate calculation of the a1 fundamentals and a CNDO/S-Cl calculation. The agreement between the calculated and observed values of ν6 and ν8 CC stretching frequencies confirms the orbital nature of the T1 state.
