Abstract:	Conclusions The present ESR study on the¹³C enriched carbonate apatites suggested that the doublet signal of 146 gauss disposed on either side of the asymmetric signal is a hyperfine splitting due to¹³C. The doublet signal of 170 gauss which has been observed in enamel samples by several workers is tentatively attributed to another hyperfine splitting due to¹³C.
