Raman spectroscopic analysis of graphite. a Reflected light image of graphite showing the locations of point analyses and the line-stepped scans. b Raman spectra of point analyses of graphite for (1) the grooved band, (2) the flat part, and (3) the covered part. c Line-stepped scan of the graphite surface. The blue data indicate the value of R1 and the red data indicate the R2 values. The yellow shading indicates the locations of grooved bands
