Electron paramagnetic resonance investigation of irradiated lithium acetate dihydrate and mercuric acetate single crystals

Abstract

An electron paramagnetic resonance study of X-ray irradiated single crystals of lithium acetate dehydrate and mercuric acetate has been made. The CH(2)CO(2) radical has been identified in lithium acetate dehydrate at liquid nitrogen temperature. The HCH angle was found to be 118(o)2 + 2.0(o). The principal elements of the hyperfine tensor and the g tensor were calculated. Mercuric acetate irradiates at liquid nitrogen temperature showed the presence of two CO(2) species. Spectra at -80 degrees C showed the presence of two CH(2)CO(2) radicals. The principal values of the hyperfine tensor for the two magnetically distinct sites were obtained.
