Soft X-ray Absorption Spectroscopy for Observing Element-specific Intermolecular Interaction in Solution Chemistry

Soft X-ray absorption spectroscopy (XAS) observes element-specific intermolecular interactions of light elements in liquid phase through the core-to-valence excitation. We have newly developed liquid cells and devices with precise photoabsorbance control. We demonstrate here their applications to XA...

Description
Summary:Soft X-ray absorption spectroscopy (XAS) observes element-specific intermolecular interactions of light elements in liquid phase through the core-to-valence excitation. We have newly developed liquid cells and devices with precise photoabsorbance control. We demonstrate here their applications to XAS in transmission measurement with aqueous acetonitrile solutions and XAS in fluorescence-yield measurement with microfluidic systems.
