These crystals have been irradiated with Co-60 gamma-rays at room temperature. The crystals have been investigated by an X-band electron spin resonance (ESR) spectrometer two days after irradiation. Very strong ESR peaks have been observed at the temperatures between 130 and 430 K. However, a line broadening has been observed at 130K. Also analyses found that EPR specra are temperature-dependent and show anisotropic behaviour.en10.1080/10420150600929396info:eu-repo/semantics/closedAccessEPRbenzo[c]cinnolineEPR parametersfree radicalArticle16205.06.2020341344Q3WOS:000248415200005Q4
