Photodissociation of Vinyl Chloride: Formation and Kinetics of Vinylidene H2CC(3B2)

Article abstract of DOI:10.1021/j100259a039

The primary photodissociation processes in the photolysis of vinyl chloride have been investigated by using the flash photolysis-kinetic spectroscopic technique.Concentrations and temporal profiles of product H2CC(³B₂), HCl, and C2H2 are monitored by their absorption in the vacuum ultraviolet at 137, 139, and 151 nm, respectively.HCl and H2CC(³B₂) are formed with the same time history via a 1,1 elimination from excited C2H3Cl.Rate constants for the interaction of H2CC(³B₂) with He, 1.07 +/= 0.17E-14 cm³ molecule^-1 s^-1, and C2H3Cl, 3.5E-11 cm³ molecule^-1 s^-1, have been obtained.
