Interaction of HCl with a beta-NAT Surface: Prediction of the IR Spectrum

Heterogeneous reactions that take place over the surface of polar stratospheric cloud (PSC) particles are thought to play an important role on stratospheric ozone depletion. Chlorine reservoir species, such as HCl and ClONO2, adsorbed on those particles, can be converted to reactive chlorine compounds, responsible for the destruction of ozone. The high temperature phase of nitric acid trihydrate (β-NAT) is one of the most important constituents of PSC.
