We investigate multiphase chemistry of atmospheric relevance at the air-water and air-solid interfaces at the SIM & Phoenix & ISS endstation at SLS and the ALS at the Lawrence Berkeley National Laboratory. This addresses the structure of the interfacial hydrogen bonding network, the observation of reaction intermediates at the surface, following interfacial acid-base chemistry, and monitoring the oxidation at environmental surfaces. We develop X-ray excited electron spectroscopy for atmospheric research at the Swiss Light Source. The approach combines our know-how in dosing and detecting atmospheric trace gases and Near Ambient Pressure photoemission (NAPP) and X-ray absorption.
