✦ Synopsis

The COz-laser-induced IRMPD of CF2C12/HI and CF*ClBr/HI mixtures produced "C-enriched CF,HCI. In CF#&/HI mixtures, the CF,HCI underwent secondary IRMPD in the continuing pulse irradiation at the same wavenumber and fluence, yielding CFzHz with a "C content of 97%. Because of efficient decomposition at relatively low fluences, CF,CIBr seems to be a promising starting molecule in two-step "C enrichment,
