The study of extraterrestrial samples returned from the Moon, asteroids, and via meteorites has the potential to inform problems relating to the oxidation states of multivalent cations and the distribution of oxygen in our Solar System. For more than 25 years, our group has worked to develop XAS methods for analyzing the partial pressure of […]

Spin and oxidation state sensitivity of 3d metal K-edge X-ray Emission Spectroscopy (XES) has been utilized in recent years to successfully probe the ultrafast spin transition and electron transfer processes in femtosecond time-resolved experiments . In this talk I will present the results from a combined time-resolved Fe Kα and Kβ XES and X-ray Solution […]
