Abstract: EPR technique has been used to study the electronic structure of nitrogen impurities in synthesized diamond with pretreated graphite. The observed hyperfine splitting lines of 14N reveals the presence of for types of substitution nitrogen. A quantitative way has been proosed to estimate the spin concentration of the nitrogen impurities. The analytical result indicates that the spin concentration of nitrogen in diamond synthesized with pretreated graphite is higher than that of synthesized with normal graphite.
