| Abstract: | Two kinds of the phosphorus-centered radicals produced from hydrogen atom abstraction by2,2-diphenyl-1-picrylhydrazyl (DPPH) were trapped by N-tert-butyl-a-phenylnitrone (PBN) and5,5-dimethyl-l-pyrroline N-oxide (DMPO), and investigated by means of EPR spectroscopy.The spin adducts with a characteristic hyperfine coupling constant(hfcc) caused by a phosphorusatom were observed. Based on the hfcc values caused by the phosphorus and hydrogen atoms,the conformational positions of the adducts trapped by PBN and DMPO are discussed. |
