Title
Vacuum ultraviolet photoabsorption of pure solid ozone and its implication on the identification of ozone on Moon
Abstract
In this Letter we present, for the first time, VUV (109-220 nm) photoabsorption spectra of high density amorphous and crystalline forms of O$_3$ relevant to both planetary/satellite and InterStellar Medium (ISM) conditions. Absorption in the Hartley region was observed to be very weak or absent when pure O$_3$ ice was formed in the crystalline phase. Our results suggest that pure solid O$_3$ effectively absorbs in the Hartley band but only at temperatures $łt$70 K. Such results suggest the need for in-situ techniques to detect the presence of O$_3$, which otherwise is a minor constituent in the lunar exosphere.
