Abstract: The quenching of electronically excited uranyl ion with aromatic hydrocarbons and related compounds has been measured using a UV-visible spectrophotometer. The lack or presence of aromatic n-electron cloud, extent of positive inductive effect due to methyl substituents on benzene ring and extension of aromatic n-electron cloud determine the order of quenching action of the aromatic hydrocarbons. Triphenylphosphine oxide formed during the photochemical reduction of uranyl ion with triphenylphosphine also quenches excited uranyl ion.
