Abstract

Abstract: Active intermediates produced in the photolysis of benzaldehyde and p-bromobenzaldehyde have been investigated by the spin trapping technique and ESR spectroscopy. The results show that the free radicals C₆H₅CO, p-BrC₆H₄CO, C₆H₅, and p-BrC₆Hi are formed in the primary processes; and the free radicals C₆H₅CHOH and p-BrC₆H₄CHOH are formed in concentrated solution.

Key words: photolysis, benzaldehyde, ESR, intermediate, free radical
