Abstract: Rotationally-resolved vibrational spectra of trimethlyene oxide (c-C$_{3}$H6O) from 650 through 1200 \wn were recorded using far infrared synchrotron radiation at the Canadian Light Source with better than 0.001 \wn resolution. The observed bands correspond to at least eight different fundamental vibrations in this region. Due to the low frequency ring puckering motion,\footnote{G. Moruzzi \textit{et al.}, \underline{J. Mol. Spectrosc.} \bf{219}, 152 (2003).} the observed rovibrational pattern of each band is congested with hot-combination bands that originate in the first two excited ring puckering states (52.9 \wn, 142.6 \wn). The ongoing analysis of the strong \textit{b-type} bands corresponding to asymmetric in-plane CO stretching ($\nu$$_{10}$:1008 \wn)\footnote{B\'{a}nhegyi \textit{et al.} \underline{Spectrochim. Acta.} \bf{39A}, 761 (1983).} will be discussed along with the identification of allowed Coriolis interactions arising from nearby energy levels related to in-plane CC stretching ($\nu$$_{9}$: 940 \wn, $\nu$$_{3}$: 1033 \wn).
