Data from L.P. Chen et al provide new insights into metals

"Inelastic X-ray scattering (IXS) spectrum provides a powerful tool to investigate the electronic structure of organic materials, in complimentary to the conventional optical spectra," scientists writing in the journal Synthetic Metals report. "Starting from a single molecule, then a dimer, and finally a cluster of molecular aggregate, we developed a Frenkel exciton model to describe the IXS process based on the quantum chemical calculations for the molecular excitations in the organic crystal of open-ring photomerocyanine form of spirooxazine (Py-SO). It is shown that the quantum chemical calculation combined with Frenkel exciton model can well describe the...
