Abstract
The MW-spectra of trans- and gauche-rotamers of 5 isotopes of ethylchlorosilane have been measured and partially analyzed. From the analysis rotational constants, centrifugal distortion constants and nuclear quadrupol coupling constants have been obtained. The determination of the restructure from 30 rotational constants leads to different bond angles C -C -Si for the two conformers. The optimalization of the quadrupol coupling constants in the bond axis system on the basis of the r0-structure using all information on the 35Cl-species yields the following values: ZZZ = (-35.5±0.8) MHz, η = - 0.25±0.11 for the trans-form and ZZZ= (-36.3±2.7) MHz, η = -0.08±0.10 for the gauche-form.Keywords
