Spectroscopy and Lifetimes of the 1(2)Piu State of Na+<INF POS="STACK">2: A New Comparison between Theory and Experiment.
A detailed theoretical study of the spectroscopy of the 1(2)Piu state of Na+<INF POS="STACK">2 is presented, including the determination of Dunham coefficients from recent effective potential calculations of the Na+<INF POS="STACK">2 molecular potential curves. We emphasize the discrepancies existing among several experiments and among several theoretical models available in the literature. The radiative lifetime of the rovibrational levels of the 1(2)Piu state are also computed and are found in agreement within 20% with experiment. Copyright 1998 Academic Press.
