Induced absorption spectra of a crystal violet dye
Using the pump-probe method, the short-lived induced and long-lived absorption capacity of a crystal violet (CV) dye is studied in various solvents. The solvents selected for this study are water, dimethyl sufoxide (DMSO), and isopropyl and ethyl alcohols. The formation of triplet-triplet states of...

| 520 | 3 | |a Using the pump-probe method, the short-lived induced and long-lived absorption capacity of a crystal violet (CV) dye is studied in various solvents. The solvents selected for this study are water, dimethyl sufoxide (DMSO), and isopropyl and ethyl alcohols. The formation of triplet-triplet states of CV is observed in these solvents under excitation by the 4-th harmonic nanosecond radiation of a Nd:YAG-laser (wavelength 266 nm, average power 25.5 mW, pulse repetition frequency 3 Hz, pulse duration 10 ns, and peak power 10−12 MW/cm2). It is shown that the nonstationary spectra of induced absorption of CV in ethanol contain two bands at 400 and 485 nm. In isopropyl alcohol, both singlet-singlet and long-lived triplet-triplet absorption of CV > 17.2 ns is recorded at room temperature in the region of 400-500 nm. | |
