Mixtures of BCl3 and HzS are irradiated with 10.55 pm radiation (P( 16) line of the 001-100 band of COz) from a TEA Iaser. After several hours of irradiation it is found that the maximum "B to "B ratio ofrecovered gaseouk boron contain- ing materiall(~rimarily unreacted BClg) is 0.413 i 0.004. The c

β¦ Synopsis
Chlorine iSOtOpiG abundances were significantly altered bf lasei tiduced. selective excitation of particti isotcpic species of thiophosgene followed by a chemical reaction between the electronically excited $Gphosgene and diethoxyethylene. The concentration of 35Cl in thiophojgene was changed from 75% to 64% or 8m depending upon +-he isotopic species inititiy excited.

A number of lines from a CO2 TEA laser were used to photolyze CF2C12. Enrichment of the 35C1 and "Cl isotopes in the molecular chlorine formed durmg the photolysis was observed using a mass spectrometer. Maximum enrichment was about 1.8. The dependence of enrichment on wavelength, reactant concentra
