Pure rotational spectra of gaseous CH 3 SiH 3 in the two interacting torsional states (£ 12 Å 0, £ 6 Å 3) and (£ 12 Å 1, £ 6 Å 0) were observed in the region from 87 to 197 GHz using a mm-wave spectrometer. Here £ 12 and £ 6 are, respectively, the principal quantum numbers for the silyl rocking mode

✦ Synopsis
High-resolution Fourier transform spectra of HDSe in the region of the 2 3 and 3 3 bands were recorded and analyzed for five different M Se isotopic HDSe species. Energies obtained from rovibrational analyses of the ( 002) and ( 003) states, together with those taken of the (001) state from an earlier study [O. N. Ulenov, G. A. Onopenko, N. E. Tyabaeva, H. Bu ¨rger, and W. Jerzembeck, J. Mol. Spectrosc. 198, 27-39 (1999)], were used as input information for a "Global Fit" procedure. This fit provided 34 spectroscopic parameters for the HD 80 Se species which reproduced rotational-vibrational transitions of the ( 001), (002), and (003) states within experimental accuracy. Corresponding analyses were performed for the other M Se (M ϭ 82, 78, 77, and 76) species.
