Title: Photolysis of 1,1,1-difluorochloroethane (Freon 142) at 147 nm

Journal/Source: Int. J. Chem. Kinetics, 9, 697-703, (1977); https://doi.org/10.1002/kin.550090502


Data: diagram, table

Energy/Wavelength range: 147 nm

Resolution: 

Temperature: 296 K

Temperature dependence: no

Pressure/Concentration: 3.6 - 20.6 Torr

Phase: gas

pH:


Comments: The molecule photodecomposes largely by alpha, beta elimination of HCl to give 1,1-difluoroethylene ( PHI = 0.74 ± 0.06). 
The effects of added NO, H2S, and CF4 were investigated. The extinction coefficient at 147 nm and 296 K is given.
