Infrared Spectrum of the Primary Ozonide of Ethylene in Solid Xenon

Separate Xe/O3 and Xe/C2H4 mixtures were condensed on a CsI window at 50 K and then warmed to 80-100 K.Strong infrared absorption due to the secondary ozonide and weaker bands at 409, 647, 727, 846, 927, 983, and 1214 cm^-1 replaced the ethylene and ozone absorptions.The latter new bands agree with earlier solid film and CO2 matrix studies and are assigned to the primary ozonide.Isotopic substitution (16,18O3, 18O3, CH2CD2, C2D4, 13C2H4) provides a sound basis for vibrational assignments.A sextet splitting for the 647-cm^-1 antisymmetric O-O-O stretching mode in the 50percent oxygen-18 enriched experiment confirms the primary ozonide structure and directly characterizes the weak O-O-O single bonds.
