 Title: ANALYSIS OF THE RING-PUCKERING SPECTRA OF 1,3-DISILACYCLOBUTANE AND ITS $1,1,3,3-d_{4}$ DERIVATIVE. Creators: Irwin, R. M.; Cooke, J. M.; Laane, J. Issue Date: 1976 Abstract: The low-frequency infrared and Raman spectra of 1,3-disilacyclobutane, $H_{2} \overbrace{SiCH_{2} SiH_{2}C}H_{2}$, and its $d_{4}$ derivative have been analyzed using the usual quartic-qudratic potential energy function for the ring-puckering vibration. A puckering model which allows rocking of the $SiH_{2}$ groups was utilized in order to obtain the kinetic energy expansions. The incorporation of the rocking motion permits analysis of the data for both isotopic molecules with the same potential energy function, which has a barrier to inversion of $87 cm^{-1}$.
