N2 - Three intermediate-lying Rydberg 1Δg states of 39K2 were studied by CW optical-optical double-resonance (OODR) spectroscopy. The absolute vibrational numbering, the Dunham coefficients, the Rydberg-Klein-Rees (RKR) potential curves, and the Franck-Condon factors (FCF) of three (nd)1Δg-B1Πu systems are given. The variation with the principal quantum number n of the contribution of the ndδg Rydberg electron to the binding energy is discussed. In addition, five observed successive (nd)1Δg states included in this work (n = 8, 9, and 10) and the work of Wang et al. (J. Chem. Phys., in press) (n = 6 and 7) are assigned absolute electronic state numbering based on the molecular building-up principle. Furthermore, the dissociation limits, the dissociation energies, and the quantum defects of those (nd)1Δg states are compared with respect to the asymptotic assignments made by Broyer et al. (Chem. Phys. Lett. 99, 206-212, 1983) and by Kowalczyk et al. (Z. Phys. D. 13, 231-240, 1989); our work supports the assignment of Broyer et al.
