Abstract

The free-jet rotational spectra of the normal and S-34 isotopic species of tetrahydrothiophene (THT)-argon have been investigated with either an absorption millimetre-wave or a Fourier-transform microwave spectrometer in the 60-78, and 6-18.5 GHz frequency ranges, respectively. Analysis of the rotational constants has provided two mathematically possible locations for the Ar atom, above or below the ring of THT. The determined distance Ar-CMTHT is R = 3.912(8) Angstrom, the Ar-CMTHT-S angle is theta = 80.1(16)degrees and the two possible values of the dihedral angle Ar-CMTHT-S-C-4 are phi = 69.5(12)degrees or 98.5(13)degrees. From the centrifugal distortion constant D-J the dissociation energy of the complex has been estimated to be 2.1 kJ mol(-1).
