摘要
The microwave spectrum of (CH3)(3)SiCl and its isotopic species (CH3)(3)(SiCl)-Cl-37, (CH3)(3)(SiCl)-Si-29, (CH3)(3) (SiCl)-Si-30, and ((CH3)-C-13)(CH3)(2) SiCl has been studied in the frequency range of 3 to 40 GHz. The barrier to internal rotation, the chlorine quadrupole coupling, and the structure were determined. Ab initio calculation were compared with the experimental results.
