Notes:
For the nf (l=3) series of Na2, quantum defects are calculated from theoretical values of the core quadrupole moment and polarizabilities. They compare favorably with those inferred from our preliminary report of high resolution all-optical triple resonance spectroscopy [Chem. Phys. Lett. 236, 553 (1995)] and from the full report of such spectra given here. The spectrum is the simplest when the higher intermediate state has J′=0 which requires a final state J=1. We predict the stroboscopic effect should first occur when n=52 for the nf series, as we observe, rather than at n=69 for the np series. Our data thus confirm that the strongest series is the nf. Hence the ionization potential is not 39 478.75±0.04 cm−1 as previously reported, but rather 39 478.101±0.013 cm−1, implying a molecular ion dissociation energy of D00(Na2+)=7914.038±0.014 cm−1. © 1999 American Institute of Physics.
