Using the picosecond spectra-streak method we monitored the dynamics of preferential solvation of a charge-transfer dipole in binary mixtures of solvents strongly different in dielectric constant. The observed slow (0.25-l ns) spectra1 red-shift of the charge-transfer (exciplex) fluorescence is cons
The use of chemical probes for the characterization of chemical properties was explored for completely non-aqueous aprotic binary solvent mixtures. The Dimroth-Reichardt E T (30) betaine dye, 4-nitrophenol, 4nitroanisole, 4-nitroaniline and N,N-diethyl-4-nitroaniline were used to study preferential
