[en] The authors have observed high resolution ¹³C NMR spectra in pristine HOPG and K- or SbCl₅-intercalated compounds. The sample was either a block or a slice of HOPG. The spectra of K-intercalated 2, 3, 4 and 6 stage compounds consisted of 2, 3, 4 and 6 lines, respectively. These lines were assigned to bounding and interior graphite layers. The T₁T of each resolved line was measured and the density of states distribution at the Fermi level was determined for the bounding and interior layers. Some features of SbCl₅-intercalated compounds are compared with K-intercalated compounds. (Auth.)
