Abstract

Infrared laser conversion of chlorodifluoromethane (CF2HCl) enriched in 13C to 31%, to dibromodifluoromethane (CF2Br2) with the same enrichment has been studied. Optimum conditions have been found, and effective laser synthesis of macroscopic amounts (1 g) of CF2Br2 has been carried out. IR absorption spectra of synthesized CF2Br2 with a 13C concentration of 31% have been recorded. The 13C isotope shifts of the ν1, ν6, and ν8 modes have been measured.
