In this work we present a theoretical and experimental study of the {ital i} {sup 3}{Pi}{sup {minus}}{sub {ital g}}{r arrow}{ital b} {sup 3}{Sigma}{sup +}{sub {ital u}} transition dipole moment in molecular hydrogen. By means of translational spectroscopy the functional dependence on internuclear distance of the transition dipole moment was directly probed. Selective excitation of the {ital i} {sup 3}{Pi}{sup {minus}}{sub {ital g}}, {ital N}=1 level, being unaffected by rotational couplings with other 3{ital d} singly excited states, allows for straightforward comparison with {ital ab} {ital initio} calculations. Excellent agreement is found.
