ResumoAn investigation of the triplet 3d-complex of H2, the g(3d) 3Σ g +, i(3d)3Π g , and j(3d)3Δ g states and the nearby h(3s)3Σ g + state, has been undertaken. Approximately 50 g-factors have been measured by optical Zeeman spectroscopy, for the 3d levels for v = 0–3, N ⩽ 7. A concomitant calculation of the L-uncoupling effects and the corresponding eigenvectors in a Hund's case (b) basis has been performed. The accuracy of this calculation is assessed by comparing the experimental g-factors with those predicted by the calculation. For the overwhelming majority of levels, there is good agreement between the predicted and observed g-factors. It is shown that the presence of the h(3s) 3Σ g + state is important for low rotational level (N ⩽ 2) g-factors, but it is considerably less important for higher levels.
