Abstract

Electron paramagnetic resonance (EPR) spectroscopy is used to investigate UV-irradiation damage in amorphous sulfur by examining post-irradiation kinetics as a function of UV-exposure time. The kinetic study is described by first-order concurrent reactions where the sulfur, as reactant, undergoes two parallel processes leading to the formation of two distinct defects called S-1(center dot), and S-2(center dot). The temperature dependence of the EPR intensities of the signals, related to these defects, is used in the kinetic study. (c) 2005 Elsevier B.V. All rights reserved.
