Advantages of X-<strong>ray</strong> Raman ? Measure S(q,ω) (finite q) • Element specific • Bulk sensitive • Spectroscopy of dipole forbidden transitions (e.g. d-d, f-f ) • Direct coupling to charge • Spectroscopy in the presence of • Electric fields • Magnetic fields • High pressure • High temperature • ….. • High energy resolution (given by monochromator, analyzer and final state widths)
