研究了氢分子三种稳定同位素变体的近阈高束缚态。许多扰动和意想不到的转变，观察到远至1厘米-1以下的第二个解离阈值。这种复杂的结构可能是由B、B′、C电子态之间的非绝热耦合、精细和超精细相互作用引起的微扰以及强形状共振的组合引起的。扰动的近阈值状态和振动连续表现出细粒度的结构，同位素之间的差异很大，因为不同的非绝热耦合。
The near-threshold highly bound states of all three stable isotopic variants of molecular hydrogen have been studied. Numerous perturbations and unexpected transitions are observed as far as 1 cm-1 just below the second dissociation threshold. This complex structure may arise from a combination of nonadiabatic coupling between B, B′, C electronic states, perturbations due to fine and hyperfine interactions, and strong shape resonances. The perturbed near-threshold states and vibrational continuum exhibit finegrained structure, differing greatly between isotopes because of varying nonadiabatic coupling.
