We report the identification of stable measurements have been carried out over the range of 18-130 Ghz in a cooled septum abosrption cell. Preliminary analysis of the spectrum provides convincing evidence that the dioxymethane intermediate observed has the stable ring structure (figure), rather than the biradical or zwitterion form, with k=+ 0.447 and $\mu _{b} =2.7 \pm 0.2 \$D. The final results for this species and several isotopic forms will be presented. en_US dc.format.extent 184629 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title OZONOLYSIS OF ETHYLENE, MICROWAVE SPECTRUM OF DIOXYMETHANE $(H_{2}COO)$ en_US dc.type article en_US
