摘要：
The 3 1Πg and 3 1Δg states of K2 have been observed for the first time via the intermediate levels of the A 1Σu+ and B 1Πu states using optical-optical double resonance (OODR) excitation spectroscopy. The absolute vibrational numberings are obtained by comparing the calculated Franck-Condon (FC) factors with the excitation intensities and resolved fluorescence spectra. The Rydberg-Klein-Rees (RKR) potential curves are determined with the fitted molecular constants. The dependence of the molecular constants on the principal quantum numbers for the bonding and antibonding orbitals and the quantum defects are discussed. The adiabatic and diabatic dissociation limits for those states are given based on comparison with theoretical calculations. © 1995 American Institute of Physics.
