摘要
We present picosecond time-resolved resonance Raman spectra that demonstrate formation of the iso-CH2Br-I species following A-band excitation of bromoiodomethane in cyclohexane solvent at room temperature. The isoCH(2)Br-I species is produced within several ps and appears to decay with a half-life on the 2-3 ns time scale. We compare these results to previous studies on solution phase photodissociation of dihalomethanes. (C) 2001 Elsevier Science B.V. All rights reserved.
