Abstract

Aerosols of ozone have been generated in a collisional cooling cell and observed over a small temperature range viaFTIR spectroscopy, with the phase transition from the vapour taking place in the range 80–84 K. The condensed phase bands at 1038 cm−1 (ν3) and 2105 cm−1 (ν1 + ν3) were assigned to the liquid phase. Aerosols were also generated from mixtures of ozone and HCl. In the presence of liquid ozone aerosols, evidence of solvated HCl was observed via a broad IR band 2795 cm−1. Notably, production of a metastable, amorphous solid phase of HCl (exhibiting a narrrow band at 2780 cm−1) was favoured to the extent that it could be generated in large excess over the crystalline orthorhombic form that usually dominates at 80 K.
