Analysis involving the linear solvation energy relationship (LSER) of the energy of maximum fluorescence of seven structurally related probes in a micellar medium has been made to obtain solvation properties of the aqueous micellar phase. Solvation interactions as expressed by the empirical Kamlet−Taft solvatochromic parameters representing dipolarity/polarizability (π*), hydrogen bond donor acidity (α), and hydrogen bond acceptor basicity (β) have been determined for aqueous micelles formed by cetyl trimethylammonium bromide, sodium dodecyl sulfate, and Triton-X 100. The parameters agree well with those reported by other workers using absorption probes. Solvatochromic measurements also allowed the determination of partition coefficient values for the probe molecules between the micellar and the aqueous phase. The observed values have been rationalized in terms of different modes of solute−solvent interaction.
