Raw. Dryfe et al., TIME-RESOLVED LASER-INDUCED FLUORESCENCE STUDY OF PHOTOINDUCED ELECTRON-TRANSFER AT THE WATER 1,2-DICHLOROETHANE INTERFACE/, The journal of physical chemistry. A, Molecules, spectroscopy, kinetics, environment, & general theory, 101(14), 1997, pp. 2519-2524
Time-resolved laser-induced fluorescence in total internal reflection
mode has been used to monitor the lifetimes of excited species located
within the evanescent wave on the aqueous side of the water/1,2-dichl
oroethane interface, in the presence of varying concentrations of quen
cher molecules in the adjacent organic phase. The aqueous chromophore
used was europium(III), with anthracene being employed as the organic
quencher. The kinetic data are obtained from analysis of the relevant
mass-transfer regime. The heterogeneous electron transfer rate constan
t between the two species was found to be 1.9 x 10(-4) m(4) mol(-1) s(
-1).
