Program Description
The protein cytochrome c plays an active role in biological processes in humans and animals. The knowledge of the electronic structure of this protein including bonding and reaction properties related to the valence state of its central iron ion is crucial, but difficult to address directly. In this study, the hard X-ray based method of resonant inelastic X-ray scattering (1s2p RIXS) will be introduced together with its application to investigate the protein's bonding properties. 1s2p RIXS is a powerful method that allows the study of systems in difficult conditions with the resolution of soft X-ray absorption spectroscopy.
Here, this presentation serves two goals: The introduction of 1s2p RIXS in terms of bonding property extraction through experiment and theory, and the use of this information for the electron transfer and apoptosis mechanisms using SSRL and LCLS.
