摘要: During electron paramagnetic resonance (EPR) studies of shales and related samples, it was found that the signals from these samples overlapped strongly those internal standards commonly available, such as DPPH (1,1-diphenyl-2-picryl-hydrazyl), nitroxides, pitch. This paper reports K/sub 3/CrO/sub 8/ (potassium perchromate), a Cr(V):3d compound can serve versatile standard for measuring spin concentration g values organic free radicals by EPR spectroscopy determining magnetic moments static susceptibility techniques.
