The torsional spectrum of CH3SiH3

The Forbidden RotationalQ-Branch of CH3CF3: Torsional Properties and (A1−A2) Splittings

“…[9] using straightforward methods (15). The matrix elements of H Ј D have been discussed previously (27). The matrix elements of H Ј S are of two different types.…”

High-Resolution Far-Infrared Torsional Spectrum of CH3SiD3 Using a Synchrotron Source

“…This is necessitated by the fact that nearly all vibrational states (usually bright) are embedded in a torsional bath (largely dark in absorption) (1,2). A large number of experiments on the gs were carried out using molecular beam (3), microwave (4-6), mm-wave (5-7), and infrared spectroscopy (8)(9)(10). As a result, the torsional energy for the gs was determined with high accuracy.…”

Millimeter-Wave Spectra of CH3SiH3in the Two Interacting Torsional States (v12= 0,v6= 3) and (v12= 1,v6= 0)

“…This difficulty appears to be experimental in origin, as the corresponding because the error e for the infrared transitions in Refs. (1,6,8) was chosen conservatively to allow for potential blending lines for higher J fit well. The values of e for the first two components are listed in Table 2.…”

“…This agreement is indicative of the fact that the perturbation due to the nearby vibrational state on methyl silane. Any notation which is not explicitly defined here follows that used earlier (1,(6)(7)(8)10). (£ 5 Å 1), the Si-C stretch, is a homogeneous one.…”
