Abstract

A method of photochemical separation of isotopes, wherein molecules containing differing isotopes to be separated are selectively excited by laser radiation, and the excited molecules are collectively reacted with a scavenger which is relatively inert to molecules of lesser excitation, the reaction producing a stable addition product which is readily isolatable.
