 Title: THE $\nu_{7}$ AND $\nu_{6}$ BAND SYSTEMS OF CARBON SUBOXIDE Creators: Auwera, J. Vander; Johns, J. W. C. Issue Date: 1990 Publisher: Ohio State University Abstract: The analysis of the FIR spectrum of $C_{3}O_{2} (1)$ has been completed. Bands involving excitation of up to 8 quanta of the low frequency bending mode $\nu_{7}$ have been analysed. The results will be presented. The first contribution serves as a basis for further analysis of the IR spectrum of $C_{3}O_{2}$ in the region of the $\nu_{6}$ fundamental, started four years ago (2). For this purpose, a new spectrum has been recorded from 520 to $580 cm^{-1}$ at $-60^{\circ}C$ with twice the resolution used previously, i.e. $0.002 cm^{-1}$. The analysis has been extended and preliminary results will be presented. Description: (1) J.W.C. Johns and J. Vander Auwera.
