Effective IR Laser Conversion of Carbon-13 Enriched Chlorodifluoromethane to Dibromodifluoromethane

详细

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.
