SOLVENT EFFECTS ON THE VISIBLE ABSORPTION SPECTRUM OF CRYSTAL VIOLET

Addition of polar solvents to non-polar solutions of crystal violet results in dramatic changes in the visible absorption spectra.The observed changes are explained in terms of crystal violet existing as an ion-pair in non-polar solutions and as a solvated ion in polar solutions.The spectrum of crystal violet in toluene and in acetone solution remains virtually unchanged over a wide temperature range.However in methanol, as was reported for ethanol ( 1 ), the short wavelength component of the absorption in th visible region disappears as the temperature is lowered.The spectral behaviour in alcoholic solutions suggests a decreasing solvent-solute interaction aroundf the dye cation due to increased self-association of the solvent molecules as the temperature is decreased.Our observations have a direct application in intepreting some of the results of the photodynamics of crystal violet in solution.
