Abstract
The low-temperature chemistry of thin films of water ice and the important stratospheric NOy species dinitrogen pentoxide have been investigated in order to spectroscopically characterize one of the principal heterogeneous reactions that occurs on polar stratospheric cloud particles (PSCs). This contributes to stratospheric dentrification. Using reflection-adsorption infrared spectroscopy, we have observed the formation of both covalent and ionic forms of solid N2O5 on both ice and the clean substrate. Thermal evolution experiments suggest that the solid covalent phase, which can only be formed at the lowest temperatures (T
