Comments: Samples of neat solid ozone and ozone trapped in excess ice have been subjected to laser photolysis at 308 nm. 
Cross sections for photoabsorption and photodestruction of the ozone are reported. The quantum yield decreases from 1.5 ± 0.2 
in pure ozone to 0.4 ± 0.2 for ozone in excess ice.
For pure solid ozone at 308 nm sigma = (1.7 ± 0.2) x 10-19 cm2/molecule.
