Removal of Coherent Coupling Artifact in Ground-State Recovery Experiments: Malachite Green in Water-Methanol Mixtures
نویسنده
چکیده
Wavelength-tunable pulses from a synchronously pumped cavity-dumped dye laser were compressed by using an optical fiber. The resulting 250-fs pulses were used to study ground-state recovery in malachite green solutions. The coherent coupling artifact was removed from the data by an antisymmetrizing procedure, and the resultant signals were deconvoluted in the usual manner. The ground-state recovery times are compared with data from nonlinear optical studies, and the lack of a viscosity dependence in water-methanol mixtures is discussed in terms of solvent steric effects.

The kinetics of the reaction between malachite green and hidroxide ion was studied in several binary mixtures of water with alcohols (methanol, ethanol, 1-propanol, ethylene glycol and glycerol) and aprotic solvents (DMSO). In all solvents, the selective (preferential) solvation is present. A method for estimating the dielectric constant in the solvation shell and the constant of preferential s...
