|a In an attempt to determine the forces responsible for the conformations of small ring molecules the spectra of a series of ring molecules have been recorded and analyzed. Theoretical calculations were carried out to determine the importance of subtle effects of the Hamiltonian. 1,3-Disilacyclobutane is an example of a four-membered ring molecule. The low-frequency far-infrared and Raman spectra of 1,3-disilacyclobtane exhibit a series of transitions that are characteristic of the ring-puckering vibration. The motion of 1,3-disilacyclobutane during the ring-puckering vibration was investigated by a one-dimensional analysis of the ring-puckering data for isotopically related disilacyclobutanes. The ring-puckering data was analyzed by the inclusion of kinetic energy expansions in the Hamiltonian. The expansions were calculated for a basic bisector model in which varying amounts of SiH2 rocking were included. The inclusion of kinetic energy expansions improved the fit between the observed and calculated frequencies. The model in which rocking was included fit the data better than the model in which rocking was not allowed...
