Introduction Investigations concerning the photochemical decomposition of ozone have been presented by Regener12E. v. Bahr13WarburgI4Weigert15Weigert and Bohm,6 Griffith and Shutt,’ Griffith and McWillie* and Kistiakow~ky.~ The results of their researches have been summarized by Kistiakowskyg and by Griffith ahd McKeown;’O nevertheless] it is necessary to restate briefly the experimental facts before proceeding to a discussion of the mechanism. Regener2 has investigated the equilibrium of formation and decomposition of ozone in different regions of the ultraviolet light. The light source was an aluminum arc from which in one series of experiments all light of wave lengths X
