Reactions of propene, trans-2-butene, and methylpropene with 16O3, 16,18O3,and 18O3 have been studied in solid xenon at 80 - 100 K and CF3Cl solution at 130 - 150 K.The major reaction product in solution was identified as the secondary ozonide (SOZ) from the matrix infrared spectrum.Reaction products in solid xenon for propene and trans-2-butene were SOZ, primary ozonide (POZ), and aldehyde, and for methyl propene the products were POZ, oxide, and acetone.The POZ's were characterized by an intense antisymmetric O-O-O stretching mode at 640 - 700 cm^-1.Photolysis of the propene and 2-butene SOZ's gave formic acetic anhydride, hydroxy ester, and acid-aldehyde dimer decomposition products.
