1Σu+→X1Σg+ transition moments for the hydrogen molecule

Electronic moments are given for internuclear distances, 0.5 less than or equal to R less than or equal to 50.0 bohr, for transitions connecting the six lowest (1)Sigma(u)(+) states and the (1)Z(g)(-) ground state of the hydrogen molecule. Except for the two lowest transitions, the computed moments shoNN due to 9 avoided crossings-very strong R-dependence; especially at R below 0.7 bohr. This effect is also clearly visible in the adiabatic corrections that are computed for 0.5 less than or equal to R less than or equal to 0.8. (C) 2003 Elsevier Science (USA). All rights reserved.
