Abstract

CH2ClOH, CHCl2OH, and CCl3OH were prepared by UV irradiation of CH3OH/Cl2/N2 gas mixtures. Absorption cross-sections (base e) of σ (CH2ClOH) at 1093 cm− 1= 6.16× 10− 19, σ (CHCl2OH) at 1109 cm− 1= 1.22× 10− 18, and σ (CCl3OH) at 1119 cm− 1= 8.96× 10− 19 cm2 molecule− 1 were determined. The chlorinated methanols decayed with first-order kinetics to HCl and the corresponding carbonyl compound. The decay rates increased ...
