摘要

Resonance??enhanced multiphoton ionization (2+ 1 REMPI) spectroscopy near 243 nm was used to detect H and D photofragments of the 193 nm photolysis of C2HD. Measurements were performed in a molecular beam, laser photolysis apparatus, equipped with a time??of?? flight mass spectrometer. The measured H/D ratio of 2.85±0.3 may indicate nonadiabatic surface hopping occurs between 2 3 A'and 1 3 A'and/or 2 1 A'and 1 1 A'surfaces in exit ...
