| Abstract: | We report the observation of a pronounced rotational-state dependence for the fluorescence quantum yield and fluorescence decay from the S1(0,0+1160 cm−1) state of jet-cooled 9-cyanoanthracene. We attribute these results to the effects of Coriolis rotational-vibrational interaction on intramolecular vibrational energy redistribution, which influence electronic relaxation. |
