Adiabatic energies of excited 1Σu states of the hydrogen molecule

Abstract

Accurate Born-Oppenheimer potential energy curves and adiabatic corrections are computed for the six lowest 1Σu states of the hydrogen molecule. For the 41Σu-61Σu states adiabatic term values of the vibrational levels supported by the potentials and the corresponding rotational constants are given. For the outer potential well of the 61Σu state, Franck-Condon factors are listed for the possible transitions to the H H̄1Σg state. © 2002 Elsevier Science (USA).
