Interfacial Ice Chemistry
Photolysis and Acid-Base Equilibria in the QLL and Brine. The capability of acids to form hydrogen bonds has been found essential to their dissociation. The dissociation of acids plays is a principal process in the heterogeneous chemistry of the atmosphere. This project aims at developing a fundamental understanding of interfacial chemistry in the temperature range of -40°C to 0°C. In particular, the dissociation and photochemistry of nitric acid and nitrous acid at frozen and liquid air–water interfaces has since long attracted scientific interest, most notably due to the pivotal role that this surface chemistry plays in modifying the nitrogen oxide budget and thus the oxidative capacity of the atmosphere.
