Boyd, 1979, J. Mol. Spect. {\bf 75}, 53. Additional combination differences were taken from E.~H. Fink, H. Kruse, and D. A. Ramsay, 1986, J. Mol.~Spect.~ {\bf 119}, 377. The intensities of the magnetic dipole allowed transitions were calculated using the g values given in Pickett and Boyd. Hund's case (b) nomenclature is used even though the states are closer to Hund's case (a) for low J. The J = N + 1 states correlate with $\Sigma = 0$, and the J = N $-$ 1 and J = N states correlate with $\Sigma = \pm 1$ states of p = $\pm$ ($-$1)$^J$ inversion parity, respectively. The value of Q is determined from a sum over states to J = 80.
