ABSTRACT:
There is described a method for enriching a gas-like isotopic mixture with at least one isotope, in which a mixture of CF.sub.2 Cl.sub.2 and O.sub.2 is irradiated by means of a pulsed and focalized laser beam having an optical frequency corresponding to a wave number lying in the band from 920 to 945 cm.sup.-1 to enrich the residual CF.sub.2 Cl.sub.2 with .sup.37 Cl, in the band from 1050 to 1075 cm.sup.-1 to produce COF.sub.2 enriched with .sup.13 C and/or in the band from 1080 to 1095 cm.sup.-1 to enrich the residual CF.sub.2 Cl.sub.2 with .sup.35 Cl and .sup.13 C.
