Abstract:
X-ray spectroscopy is a method, ideally suited for investigating the electronic structure of matter, which has been enabled by the rapid developments in light sources and instruments. The X-ray fluorescence lines of life-relevant elements such as carbon, nitrogen, and oxygen are located in the soft X-ray regime and call for suitable spectrometer devices. In this work, we present a high resolution spectrum of liquid water, recorded with a soft X-ray spectrometer based on a reflection zone plate (RZP) design. The RZP-based spectrometer with meridional variation of line space density from 2953 l/mm to 3757 l/mm, offers extremely high detection efficiency and at the same time medium energy resolution. We can reproduce the well-known splitting of liquid water in the lone pair regime with 10 s acquisition time.
