| Abstract: | A previous measurement of the rotational spectra of SiH3D, SiH2D2, and SiHD3 has been extended in frequency region to determine rotational constants and quartic centrifugal distortion constants. Similar observations have been performed on GeH3D, GeH2D2, and GeHD3, consisting of five, three, and three Ge isotopes, respectively, and also on SnH3D, SnH2D2, and SnHD3 with seven, three, and three Sn isotopes, respectively. The observed rotational constants were analyzed to estimate the equilibrium internuclear distance for the three molecules. |
