Notes. For each cluster of transitions (involving a common ), an intensity cutoff of a factor 4 of the strongest component is used. Frequencies, experimental uncertainties (Unc.), and residuals (fexpfcalc) are expressed in MHz; Icalc in nm2 MHz. Intensities have been determined using a partition function Q(10 K) = 259.1302 determined using Pickett’s SPCAT program. (a)The quantum number F only exists for the ortho levels (see text). (b) Predictions from the final fit.
