THE HIGH-PRECISION MILLIMETER-WAVE SPECTRUM OF (SO2)-S-32, (SO2)-S-32(NU(2)), AND (SO2)-S-34

Frequencies of a number of (32)SO2, (SO2)-S-32(nu(2)), and (SO2)-S-34 transitions have been measured between 50 and 150 GHz. The frequency d etermination error was about 1-3 kHz. Such accuracy is about two order s of magnitude better than that of previous investigations. By combini ng these data with previously available submillimeter and FIR measurem ents, greatly improved sets of the parameters of Watson's A-reduced Ha miltonian have been obtained in the I-r representation.
