Abstract

The origin of D-band of graphite has not been well understood up to date. We have carried out the Raman microscopic study of pure <sup>12</sup>C and <sup>13</sup>C graphitic carbon. The peak positions of the individual Raman bands of <sup>13</sup>C graphitic carbon downshift from those of <sup>12</sup>C graphitic carbon, and the wave number ratios of <sup>13</sup>C to <sup>12</sup>C are equal to 0.96 for all kinds of Raman band positions. This value corresponds to the inverse of square root of the mass ratio of <sup>13</sup>C and <sup>12</sup>C, indicating that all of these Raman bands can be explained by the lattice vibrational mode in the monoatomic crystal model. The degree of downshift of Raman band positions could be a good indicator to estimate the carbon isotopic ratios in graphitic material.
