Abstract : Infrared and Raman spectra of liquid, crystalline, and matrix isolated carbon suboxide have been obtained in the region 20 to 4000/cm. A previously unreported solid -solid transition has been observed at 115 plus or minus 5K, and possible structures for both crystalline phases have been inferred from the spectroscopic results. The pi(u) central carbon bending mode, nu(7), has been identified in the liquid phase at 72 plus or minus 2/cm. The problem of 'disappearing' sum bands is discussed, and a revised vibrational assignment and force constant analysis for carbon suboxide is presented. (Author)
