• The microwave spectra of four isotopic species of bromomethylsilane have been measured, <I>viz.</I>, the <SUP>79</SUP>Br and <SUP>81</SUP>Br species of BrCH<SUB>2</SUB>SiH<SUB>3</SUB> and BrCH<SUB>2</SUB>SiD<SUB>3</SUB>. The observed rotational constants have been well explained by a model of which the structural parameters have been transferred from the corresponding parameters determined for ethylbromide and chloromethylsilane. The principal quadrupole coupling constants have been determined through the analysis of the first- and second-order effects of quadrupole coupling on the hyperfine structure of the observed spectra. It was concluded, within the experimental error, that the quadrupole coupling constants tensor of this molecule has the cylindrical symmetry around the largest principal axis, the direction of which coincides approximately with the C–Br internuclear line.
