| Abstract: | Electron absorption spectroscopy has been used to measure bimolecular photophysical deactivation constant by exploiting photochemical reduction of uranyl ion with triphenylphosphine. Relative rates of bimolecular quenching follow the order SCN- > Cl- > CCl4 > CHCl3 > CH2Cl2 showing that free ionic halide and increasing number of chlorine atoms in covalently bonded alkyl halides increase the bimolecular quenching action. The increased availability of non-bonding electrons on halogen atom facilitate interaction with electron deficient species (excited uranyl ion). |
