Notes. The table includes: assignments, observed frequencies, calculated frequencies from the BELGI-Cs-2Tops fit, residuals, line strengths, upper and lower state energy levels for dimethyl sulfide CH3SCH3 transitions from (ν11,ν15 = 0,0) (ground state), (ν11,ν15 = 1,0) and (ν11,ν15 = 0,1) (first excited torsional state) included in the fit with parameters of Appendix A. To obtain intensities, the line strengths need to be multiplied by appropriate statistical weights, the Boltzmann factor and divided by the total partition function (see Appendix D). The spin-weight statistics AA: EE: AE: EA depend on the parity of KaKc, i.e., 6:16:4:2 for KaKc: ee-oo and 10:16:4:6 for KaKc: eo-oe (Vacherand et al. 1987).

(a)

Upper and lower state quantum numbers are indicated by “and”, respectively. Energy levels of the EA, AE and EE species have a signed Ka value (Herbst et al. 1984).

(b)

Observed ground state (ν11,ν15 = 0,0) as well as excited torsional states (ν11,ν15 = 1,0) and (ν11,ν15 = 0,1) transitions in MHz with estimated uncertainties in parentheses (in kHz). Estimated experimental uncertainty are given according to the source of data. 5 kHz: MB-FTMW Aachen; 40 kHz: millimeter-wave Aachen; 100 kHz: (Vacherand et al. 1987); 50 kHz: millimeter-wave (Niide & Hayashi 2004).

(c)

Calculated line frequency in MHz with calculated uncertainty.

(d)

Differences between the experimental and calculated frequencies in MHz.

(e)

Calculated line strengths in D2 (for details of the calculation procedure, see text).

(f)

Upper state energy (cm-1) including the zero-point torsional energy.

(g)

Lower state energy (cm-1) including the zero-point torsional energy.

(h)

Symmetry species in the C C direct product; see text. The full table is available at the CDS.
