The entry is based on the files provided by the authors. It has been adjusted to meet the format and unit requirements. The calculated transitions are restricted to having uncertainties of less than 0.08 MHz and should be reliable enough for all observational purposes.
Please note that the vibrational identifiers correspond in the present calculation to the torsional quantum number m. The values 0 and 1 correspond to A and E symmetry lines, respectively, of v_t = 0. The corresponding values for v_t = 1 are –3 and –2.
The partition function values consider torsional states up to v_t = 8.
The dipole moment values were assumed to agree with those of the main isotopolog published by
