✦ Synopsis

The photolysis of n's-l,2-dichloroethylene has been investigated in the presence of 1 2

The results as a function of incident w$velength and as a function of initial cix pressure. indicate that at > 2200A the following primary processes occur:

The lifetime of the excited state yielding the above products is estimated at about 2.4 X 10-9 sec. At shorter wavelengths additional C9H2 is produced by decomposition of a vibrationally excited C BH zC1 radical.

Scavenging of the CHCICH radical by 1 2 produced trans-and cis-CHCICH1 in a ratio of 4 to I , respectively.

The photolysis of SOz at 3712 A in the presence of the 1,2-dichloroethylenes has been investigated at 22°C. The data are consistent with the SOz( 3B1) photosensitized isomerization of the 1,2-dichloroethylene isomer. A kinetic treatment of the initial quantum yield data was consistent with the forma

The photolysis of SOz at 3080 A, FWHM = I50 A, and 22°C has been investigated in the presence of cis-and trans-CzFzH2. Quantum yield measurements for the photosensitized isomerization of cis-C2FZH2 to trans-CzFzH2 have been made for a variation in the [SO2]/[czs-C2F2H2] ratio from 0.992 to 253. The
