Abstract

The electron paramagnetic resonance of -irradiated single crystal of tetra-N-butylammonium iodide has been studied for different orientations of the crystals in a magnetic field. The radical produced by gamma irradiation has been investigated at 300K. The spectra were found to be magnetic field dependent and radiation damage centers were attributed to the ( C H 2 C H 2 C H 2 CH 3) radical. The principal values of the hyperfine coupling tensor of the unpaired electron with these atoms and the principal values of the g tensor were determined and the hyperfine coupling constants were verified by computer simulation. The results were found to be in good agreement with the existing literature data and theoretical predictions. © 2012 Taylor & Francis.
