Abstract: Pulsed Fourier transform spectroscopy over the range of 8-18 GHz is shown to be an extremely useful method for the study of the rotational spectra of tetrahedral molecules. Rotational transitions were observed between all symmetry species allowed by centrifugal distortion in the ground vibrational state of $SiH_{4}$. The set of the tensorial centrifugal distortion constants was fitted up to the eighth order from 45 newly measured transition frequencies combined with data from other sources. In addition, rotational and rovibrational transitions of $CD_{4}$ and $SiH_{4}$ in the $\nu_{2}/\nu_{4}$ dyade were assigned and measured for the first time. They were analyzed together with the data from high resolution Fourier transform infrared spectra.
