Notes.

^(a)

J′, , , I′, and F′ represent the quantum numbers associated with the upper rotational level. J″, , , I″, and F″ represent the quantum numbers associated with the lower rotational level.

^(b)

Observed experimental frequency.

^(c)

Uncertainty in the observed frequency.

^(d)

Difference between the observed frequency and that derived from the fit. The full table is available at the CDS.
