Inelastic X-ray scattering spectra of liquid water and cyclohexane have been measured with 2 eV resolution for a momentum transfer range between 0.69 and 2.77 au at BL16A of the Photon Factory, KEK, Tsukuba. Observed spectra are transformed to the dynamic structure factor which is normalized by using the Bethe sum rule, and the static structure factor is obtained. From a comparison with extended CI calculations by the use of various basis sets, correlation effects are proved to be of vital importance in inelastic X-ray scattering.

X-ray scattering intensities for molecular gases have been calculated in the first Born approximation using correlated ab initio wavefunctions. The influence of electron correlation has systematically been studied for the series of molecules C2H2, CO, N2, O2 and F2. The correlation effects turn out to be very pronounced for the total and inelastic scattering and less so for the elastic scattering (where they cannot be neglected, however). Hopes are raised that the timely results will stimulate progress in the very recent research topic of gas X-ray diffraction.
