Photosensitised Decomposition of Ozone by Bromine

As a result of work on the photochemical chlorine-ozone reaction carried out at King's College, London, 1 experiments have been in progress on the bromine-ozone reaction in the hope of explaining the differences between the two reactions noted by Bonhoeffer 2 and commented on by various authors since that time. It was found that chains of considerable length were produced in certain circumstances, and to account for this and other facts, the formation of an oxide of chlorine as an intermediate product was postulated.
