Abstract
Resonant inelastic X-Ray scattering of highly oriented pyrolytic
graphite (HOPG) is observed above the C 1s threshold at different
polarization angles. It is shown that combining the polarization and
excitation energy dependence of X-Ray emission spectra makes it possible to
perform the quantitative band mapping selective to the chemical bonding
(σ and π ).
