Kinetics and Wave Length Dependence of the Photolytic Degradation of Kiton Red-S Laser Dye.
Abstract
The laser dye Kiton Red-S in ethanol was degraded using continuous radiation and pulsed radiation from the flash lamp of a dye laser. Data from infrared spectrograms was used to construct plots of the concentration of Kiton Red-S versus the time of exposure. From these plots the rate equation was determined. The effect on the rate of reaction of different oxygen concentrations was observed. Qualitative information from the infrared spectra was used to identify photo products. The fluorescence and power were monitored during the pulsed laser experiment to determine the primary effect of the photo products. The reaction was found to be zeroth order in Kiton Red-S and the presence of oxygen accelerates the reaction. The products were found to be esters and carboxylic acids. The effect of the products on the laser was to absorb the pump radiation. (Author)
