Abstract
The infrared spectrum of C3O2 has been studied in the vapor phase from 2.2 to 20μ with a Perkin-Elmer double-pass spectrometer, and the Raman spectrum has been photographed in the liquid phase. A comparison of the Raman with the infrared spectrum shows definitely that the molecule has a center of symmetry as is required for the linear structure commonly assumed. However, the infrared spectrum cannot be explained on the assumption of a linear model; the envelopes of the principal absorption bands as well as those of the weaker combination bands have the wrong shape. It appears rather that the oxygen atoms are bent out of line with the carbons in a plane zig-zag configuration. From the rotational structure of one of the combination bands the O–C–C angle is computed to be approximately 158°.
