摘要

A setup for recording optically detected electron paramagnetic resonance (OD EPR) spectra of radical ions involved in geminate pair recombination is described. Unlike the previously developed setups of this kind, vacuum ultraviolet (VUV) radiation is used to generate radical ion pairs. The setup allows registration of EPR spectra of short-lived radical ions in liquid and solid samples by recombination fluorescence modulated by a resonance microwave field. The spectra are recorded in the mode of direct detection of the fluorescence intensity or using the phase-sensitive detection. The advantages of the photochemical generation of radical ion pairs compared to the use of X rays and fast-electron radiation are as follows: the lack of track effects on the recombination process, the possibility of studying recombination processes in thin films of nanometer thickness, the small size, low cost, and radiation safety of VUV sources.
