Abstract

The excited singlet states of diphenylhexatriene was studied by time-resolved vibrational spectroscopy. The extreme broadening of the observed vibrations reflected the very fast exchange of energy between the excited electronic states. Coherent antistokes Raman spectroscopy (CARS) lines showed the same instrumentally limited fast increase of their intensities after electronic excitation. Furthermore, Raman excitation profiles (REP) obtained by an analysis of the excited state CARS line in the range of λ1 = 707 to 750 nm showed no significant difference of the REP of different vibrations.
