Abstract

Emission spectra of uranyl trimetyl acetate dihydrate have been recorded in the presence of trimethylacetic acid and sulphuric acid in dry acetone and in aqueous acetone respectively. The triplet state of the uranyl ion, with a vibronic structure, seems to be the emitting level. Stern-Volmer quenching constants for uranyl ion luminescence with R3P (R ≡ MeO, EtO, PhO, Ph and p-tolyl), R3As (R ≡ Ph and p-tolyl), trimethylacetic acid and water have been calculated. Quenching due to oxygen has been found to be almost absent.
