Webozone is widely used to detect the presence of ozone [1]. Recently the Vacuum UltraViolet (VUV), 110 nm – 190 nm, photoabsorption spectra of pure solid ozone revealed the absence of Hartley band while ozone con-centrations are low [3]. This could be one reason for the weak absorption in the Hartley band in Iapetus WebOzone absorbs in the band of0.200-0.320 /zm ( Hartley band) of the U V part of the spectrum and also in the visible range between 0.450 /zm and 0.700 /zm wavelengths (Chappuis band). A smaller absorption band can be identified in the infrared part of the spectrum. The strongest absorption is measured in the Hartley band.
