Rate enhancements for the reaction between Ni2+(aq) and pyridine-2-azo-p-dimethylaniline (pada) have been investigated by the stopped-flow technique in micellar solutions of a related group of anionic surfactants: the sodium alkoxycarbonylmethanesulfonates, the sodium 1,2-bis(alkoxy- carbonyl)ethanesulfonates, and the disodium 4-alkyl3-sulfonatosuccinates. The second group differs from the first in having an extra identical tail and the third from the first by having an extra polar head. The hexyl, octyl and decyl members of each group were chosen for study except for the second group where the decyl member proved insoluble. The kinetic analysis revealed that adding a second tail did not dramatically increase the binding of pada to the micelles so that rate enhancements were not much increased. Adding a second head decreased the binding of Ni2+ ion to the micelles so that the third group appears to have no advantages in rate enhancements.

In studying the radiationless energy transfer between unlike molecules (heterotransfer) in fluid and rigid solutions the fluctuations of the concentration of the acceptor molecules, as well as the dependence of the probability of resonance excitation energy transfer on the mutual orientation of the transition moments of the interacting donor and acceptor molecules have been taken into account. With these and the assumptions of the shell model of a luminescent centre (A. Kawski and J. Kaminski, Z. Naturforsch. 29 a, 452 [1974]) one obtains the Förster expression for the quantum yield of the donor fluorescence quenched by foreign absorbing substances
