“…For the lower three curves, our computed excitation energies agree within 1% with the experimental data. For the 7 and 8'2; curves, the vibrational numbering proposed by Taylor et al (1981) is not certain and leads to excitation energies larger than the computed ones. By increasing the vibrational quantum numbers by one to three units, we obtain more reliable Table 1.…”

Two-electron model potential calculations are presented for the 4-8'2; intermediate Rydberg states of Na,. The theoretical spectroscopic constants agree within 1% with the experimental results of Taylor er al. Two Rydberg series are identified; for one of them, the molecular quantum defect curve reveals a strong resonant character. Diabatic calculations show that the perturbation of this series is mainly due to an excitation of the Na: core into the two first excited states.

“…Carlson and co-workers (40)(41)(42) have identified 24 excited singlet electronic states in Na2 by this method, whereas all previous work on this molecule had only produced information about six excited states. The new levels include X, Hl, and A states from the electron configurations 3sns and 3snd, as indicated in Fig.…”

Lasers can simplify spectra by increasing or decreasing the population of a chosen level or by orienting the molecules, so that transitions involving that level can be identified. These methods reveal several series of Rydberg states in Na2, from which the constants of the ground state of the ion can be extrapolated. Many c.w. two-photon transitions, strongly enhanced by near coincidence with allowed transitions, have been identified. Unusual line shapes are found when the offset from exact coincidence is much less than the Doppler line width.
