L. Wolniewicz et al., QUADRUPOLE TRANSITION-PROBABILITIES FOR THE EXCITED ROVIBRATIONAL STATES OF H-2, The Astrophysical journal. Supplement series, 115(2), 1998, pp. 293-313
Accurate calculations of the quadrupole moment of H-2, carried out wit
h a 494 term variational representation of the electronic eigenfunctio
n, are reported, and the quadrupole transition probabilities connectin
g all the bound rovibrational levels of H-2 are presented.
