Mode-to-Mode Vibrational Energy Transfer in exp 1 B sub 2 Aniline Induced by Collisions with CO sub 2

摘要

Single vibronic level fluorescence spectroscopy was used to study intramolecular vibrational energy transfer in low pressure gas samples of exp 1 B sub 2 aniline induced by collisions with CO sub 2 . Vibrational energy transfer was traced from the O exp 0 vibronic level to eight growth levels. Collision-induced energy transfer for CO sub 2 as the collision gas was seen to follow a flow pattern similar to the pathways found previously for energy transfer in S sub 1 aniline with other collision partners. The magnitude of the normalized mode-to-mode energy transfer rate constants for each collision partner were found to vary roughly in proportion to the overall collision induced decay rate of the O exp 0 level for each system.
