N1 - Funding Information: In the amine system, rates of the two quenching process : reactions of the complex are coniparable and eficient photoreduction, $ ca. 1, results.* That the phenyl sulphides are less effective quenchers than P$C=O + K.S.CH2R aliphatic sulyhides indicates that they do not behave like phenylamines, in which nitrogen leads to increased electron density in the ring, more favourable interaction between excited species and the conjugated system, and to efficient quenching. Quenching by a sulphide arises from interac- tion at the non-bonding electrons of sulphur; electron with- drawal by the phenyl group decreases effectiveness.
