AbstractThe enrichment of the ¹³C isotope by partial photolysis of dibenzyl ketone on silica gel has been demonstrated. The ¹³C enrichment is substantial and is parallel to the increase in the probability of geminate radical recombination on a silica surface as compared with that in solution. A substantial ¹³C enrichment was also observed for the rearranged starting material, 1-phenyl-4′-methylacetophenone. The single-stage isotope separation factors are different for the two ketones although both are isomers derived from the same benzyl–phenylacetyl radical pairs.
