Özet
The electron paramagnetic resonance (EPR) spectra of gamma-irradiated single crystals of phenidone (fenidon C9H10N2O) have been studied for different orientations of crystals in a magnetic field. Phenidone single crystals have been irradiated with 60Co-γ rays at room temperature. The EPR spectra have been investigated at temperatures between 125 and 450 K. The spectra have been found to be temperature independent. The spin-Hamiltonian parameters have been obtained from the single-crystal EPR analysis. The principal values of the hyperfine coupling tensor of the unpaired electron and the principal values of the g-tensor have been determined. © 2013 Taylor & Francis.
