在14，961.7 +/-1.1MHz处观察到H_2（+）基态电子nu = 19能级的N = 1<--0纯转动跃迁。最新的理论预测，在禁戒旋转和旋转振动跃迁中，涉及解离极限附近的能级的电偶极强度很高;相关能级的束缚距离仅为0.74和0.22 cm（-1）。预计过渡的过渡时刻为0.42 D;我们的测量结果与此值一致。
The N = 1<--0 pure rotation transition in the nu = 19 level of the ground electronic state of H2(+) was observed at 14,961.7+/-1.1 MHz. Recent theory predicts significant electric dipole intensity in forbidden rotation and rotation-vibration transitions involving levels near the dissociation limit; the relevant levels are bound by only 0.74 and 0.22 cm(-1). The transition was predicted to have a transition moment of 0.42 D; our measurement is consistent with this value.
