 Title: T2N IN4. EVIDENCE OF RING PUCKERING IN DEUTERATED ANALOGUES OF TRIMETHYLENE SULFIDE Creators: Wieser, H.; Duckett, J. A.; Kydd, R. A. Issue Date: 1973 Publisher: Ohio State University Abstract: The far-infrared spectra of several deuterated analogues of trimethylene sulfide $(\alpha-d_{2},\beta-d_{2},\alpha,\alpha ^{\prime} - d_{4}$ and $d_{6})$ have been measured in the vapor phase, all showing the usual sequence of Q-branches arising from transitions between ring puckering energy states. The isotopic dependence of the double minimum potential function governing the out-of-plane motion will be discussed briefly. Several combination band progressions resulting from ring puckering-vibrational interactions, notably in the $CH_{2}$ scissoring region, are reported. It is found that for some vibrationally excited states the puckering potential function does change appreciably from its form in the ground state.
