Infrared photochemistry of trichloroethylene in the presence of oxygen

摘要

Trichloroethylene with added molecular oxygen was photolyzed with a TEA CO$-2$/ laser radiation, at v$-4$/ (933 cm$+$MIN@1$/) fundamental vibrational band for C$-2$/HCl$- 3$/ and at v$+3$/ (1020 cm$+$MIN@1$/) fundamental vibrational band for C$-2$/DCl$-3$/. The stable final products in the infrared multiphoton dissociation of trichloroethylene were determined by mass spectrometry in the 0.5 - 10 Torr pressure range of the gas. After the photodissociation process, the following final products appeared: HCl (or DCl), C$-2$/Cl$-2$/, C$-2$/Cl$-4$/, C$- 2$/Cl$-4$/O, CO, Co$-2$/ and C$-2$/O$-3$/. Experimental measurements were also performed to obtain information about the dependence of the specific dissociation rate versus laser pulse energy, for both isotopic species of trichloroethylene.
