Collisionhyphen;induced energy transfer in laserhyphen;excited dichloromethane

摘要

Laserhyphen;induced infrared fluorescence was used to measure the collisionhyphen;induced vibrational energy relaxation in dichloromethane (CH2Cl2). The activation and deactivation of the ugr;8and ugr;3/ugr;9vibrational modes was measured after excitation of CHhyphen;stretching vibrations near 3000 cmminus;1. Rate constants for the energy transfer are deduced leading to a simplified model for the vibrational relaxation in CH2Cl2.
