In the laboratory, 45Sc and 35Cl hyperfine splitting was resolved. However, since it will be resolvable in the ISM or CSM only at low values of J, only the unsplit frequencies have been predicted. The predictions at higher J should be viewed with caution because of the limited data available. Predictions with hyperfine structure are also available. The partition function does not consider the hyperfine effects ! The partition function values have to be multiplied with 32 when hyperfine splitting is considered.
The dipole moment is from an ab initio calculation in
