The microwave spectra of the title compounds, recorded in the 26.5-40.0 GHz region, are characteristic of symmetric top molecules, complicated by internal rotation and accompanied by vibrational satellites attributed to low-frequency skeletal bending modes.For Me3SiCCH, B0 = 1962.163 MHz and relative intensity measurements on the vibrational satellites give a value of 110 +/- 15 cm-1 for the degenerate Si-CC bending mode.Measurements on Me3SiCCD have been made, and the Si-C bond length has been determined as 1.83 +/- 0.01 Angstroem.For Me3SiCCCN, B0 = 711.8646MHz, whilst for Me3Si(CC)2CN, twenty broad-band symmetric-top transitions, from J = 41 to 60, have been observed and a B value of 331 +/- 2 MHz has been estimated.
