X-ray Raman Scattering (XRS, often also called nonresonant inelastic x-ray scattering), is a hard x-ray alternative to soft x-ray NEXAFS. I'll review the basic physics, including the role of momentum transfer to tune selection rules. And I'll explain Raman's involvement, or lack thereof.

In this lecture I will continue where the previous lecture ends and talk about some examples of how XRS is used to study materials under high pressure and chemical reactions.
