X-Ray Resonant Raman Spectra of Several Copper Compounds

What is it about?

Resonant effect in X-ray Raman spectra of various copper(I) and copper(II) compounds was studied by using tunable X-rays from synchrotron radiation. Prominent excitation energy dependence in spectral shape as well as in intensity was observed and analyzed in terms of simple equations derived from Kramers-Heisenberg equation. Anomaly in spectral shape was observed for Cu(II)compounds and it is ascribed to existence/nonexistence of a vacant 3d orbital in Cu(II)/Cu(I) compounds.
