Abstract
Uranyl ion is photochemically reduced to uranium(IV) in the presence o f triethylamine and triethylamine is oxidized to secondary amine and a cetaldehyde. On the basis of product analysis, temperature independent quantum yields for uranium(IV) formation and abnormal Stern-Volmer pl ots rule out the simple collisional photochemical annihilation of exci ted uranyl ion with triethylamine. Static annihilation has a significa nt contribution in addition to dynamic annihilation.
