Notes:
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 channels leading to ground state C2H(X˜ 2 Σ+ )+H(2 S) fragments in the predissociation of C2H2.
