We present the first spectroscopic identification of hitherto unknown 1,1-ethenediol, the enol tautomer of acetic acid. The title compound was generated in the gas phase through flash vacuum pyrolysis of malonic acid at 400 °C. The pyrolysis products were

Ketene and HBr were generated by photolysis of acetyl bromide in argon matrix.Of the photolysis products, ketene and HBr were trapped in the same matrix cage to form 1:1 molecular complex.The HBr stretching mode in the complex was observed at 2396 cm-1, which was displaced to 160 cm-1 below the frequency of the monomer HBr fundamental in solid argon.The DBr stretching frequency in the ketene-d2-DBr complex produced on photolysis of acetyl bromide-d3 was observed at 1717 cm-1, which was displaced to 120 cm-1 below the frequency of the monomer DBr fundamental in solid argon.After the matrices were annealed, these absorptions were shifted to 2383 and 1708 cm-1, respectively.
Photoinduced Oxygen Transfer from NO2 to Ethylene in the Vicinity of the NO2 Dissociation Threshold. A Laser Photochemical Study on Reactant Pairs Isolated in Solid Argon

The wavelength dependence of the photochemistry of C2H4*NO2 and C2D4*NO2 pairs, isolated in solid Ar, in the range 555-355 nm is reported.Continuos-wave pulsed dye lasers were used to excite the reactants, and the products were monitored by FT infrared sp
Methoxychlorocarbene. Matrix Spectroscopy and Photochemistry
Kesselmayer, Mark A.,Sheridan, Robert S.
, p. 99 - 107 (2007/10/02)
Irradiation of 3-chloro-3-methoxydiazirine matrix isolated in argon or nitrogen at 10 K gives methoxychlorocarbene.The carbene was observed by IR and UV spectroscopy.Deuterium and 18O labeling indicated significant C-O double bond character in the carbene, which was exhibited in an intense IR absorption at ca. 1300 cm-1.The time evolution and wavelength dependence of the IR bands indicate two geometric isomers for the carbene, with distinct IR absorptions.The cis-carbene shows a significantly lower energy C-Cl stretch than the trans, consistent with an anomeric interaction.Irradiation of the carbene gives acetyl chloride, ketene, and HCl in argon matrices.In nitrogen, small amounts of CO and methylchloride are also observed.Several mechanisms are proposed to explain the photochemical results.
