  Raman scattering data were collected on graphite monochromator. Spectra were
interpreted in terms of the space group $P6_3mc$, a subgroup of space group
$P6_3/mmc$. The latter has commonly been used for the interpretation of Raman
scattering data. Space group $P6_3mc$ corresponds to the buckling of graphene
sheets and is consistent with many spectral features. Both the first and second
order scattering were considered. Many first order results (most notably the
assignments of the band at 1350 and the peak at 1620 cm$^{-1}$) were found to
agree with previous observations [Y. Kawashima and G. Katagiri, Phys. Rev. B
\textbf{66}, 104109 (2002)] carried out on highly oriented pyrolytic graphite
samples. To check the consistency of the model, symmetry analysis was applied
to the second order spectra. Also a simple test for buckling model was done.
