The rates of vibrational energy decay for the S2 excited state of azulene have been measured in both monatomic and polyatomic matrix media at 4 K. We find that the existence of molecular modes in the polyatomic matrix does not substantially affect the rate of energy decay within the S1 vibrational m

โฆ Synopsis
Lime-resolved emission OC single vlbrarional level lluorescen~ from large matrix-isolated molecules has been observed for the firs1 IIme. Using the strucrured emrssion speclra rrom S, azulenc we have studred tie demiled pathways and dynamics of vibrarional energy relaxalion. TemperaLure and man-~x media erlects are used LO elucidate the detailed couphng mechanrsm which promotes energy exchange between the molecule and iare-gas media.
