J. Brown, Acta Cryst. 7:92 (1954)"" en_US dc.description Author Institution: The Harrison M. Randall Laboratory of Physics, University of Michigan en_US dc.description.abstract The infrared spectra of ethylene carbonate $(CH_{2}-O-CO-O-CH_{2}$ in the solid, liquid and vapor states and its solutions in water, chloroform, benzene, carbon tetracloride and carbon disulfide have been studied between 3600 and $400 cm^{-1}$, together with the Raman spectrum in aqueous solution. Previous X-ray crystal structure $determination^{1}$ has shown that the five-membered ring of the ethylene carbonate molecule is not planar and has symmetry $C_{2}$ in the crystal. Evidence will be presented from the spectroscopic work that the symmetry of the molecule changes from $C_{2}$ in the solid state to $C_{2{v}}$ in the other states and that the five-membered ring becomes planat. An assignment of all the observed absorption bands will be given in terms of the fundamental vibrations of the molecule. en_US dc.format.extent 93009 bytes dc.format.mimetype image/jpeg dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title THE INFRARED SPECTRA AND STRUCTURE OF ETHYLENE $CARBONATE^{\#}$ en_US dc.type article en_US
