The quantum yields (Φ) and ¹³C isotopic enrichment parameters (α) for photolysis of dibenzyl ketone in aqueous detergent solution have been measured as a function of applied magnetic field and isotopic substitution.A quantitative correlation is shown to exist between the magnitude of α and quantum yield data.The mechanism of ¹³C enrichment and the magnetic field effects are discussed and shown to be mechanistically related.
