Fine and hyperfine structure of the 2p and 3p 3PI/sub u/ states of H2

One- and two-electron fine and hyperfine structure constants of the 2p and 3p 3πu levels of the hydrogen molecule have been calculated using the 45–50-configuration elliptic coordinates wavefunctions of Rothenberg and Davidson. The two-electron integrals have been reduced to electron repulsion integrals. The resulting constants agree within 1%–5% with experiment.
