Dissociation dynamics of the A~2A'' state of vinyl radical

摘要

H or D atom velocities are reported for dissociation from several vibrational levels in the lowest 2500 cm~(-1) of the A~2A'' state of two vinyl radical isotopomers, C_2H_3 and CD_2CH. Energies are inferred for the acetylene product and compared with both theoretical and experimental work. An upper bound is given for the rate if H-atom scrambling between the #alpha# and #beta# carbon atoms.
