Abstract

Trichloroethylene with added molecular oxygen was photolyzed with a TEA CO₂ laser radiation, at v₄ (933 cm^-1) fundamental vibrational band for C₂HCl₃ and at v³ (1020 cm^-1) fundamental vibrational band for C₂DCl₃. 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), C₂Cl₂, C₂Cl₄, C₂Cl₄O, CO, Co₂ and C₂O₃. 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.
