✦ Synopsis

A large number of rotational transitions of 32S16O2, 34S16O2, and 32S18O16O have been measured in the mm-, submm-, and terahertz ( approximately 1 THz) spectral regions. These data sets have been combined with all previously measured SO2 microwave and selected far infrared data to obtain a highly precise set of ground state rotational constants for these isotopomers. The rotational constants for the three isotopomers are in MHz as follows: Parameter32S16O234S16O232S18O16O A60778.54977 (44)58991.18295 (51)59101.1690 (27) B10318.07348 (7)10318.50993 (9)9724.64284 (56) C8799.703399 (70)8761.302481 (97)8331.56018 (51) Centrifugal distortion constants up to P10 are included in the fit. A frequency listing of all the data used in the frequency range between about 7 GHz and 1 THz is included. Copyright 1998 Academic Press.
