利用差频激光光谱仪和速度调制技术在3500至2900 cm(-1)之间连续记录了NH2+的吸收光谱。分子离子是在交流辉光放电的正极柱中产生的，气体混合物为 N-2/H-2/He，比例约为 1/1/100，总压约为 7 Torr。鉴于线性度非常低(155 cm(-1))和涉及的高弯曲振动态，使用线性分子的哈密顿量对观测到的光谱进行了分析。结合之前的实验结果和从头算计算讨论了该模型的选择。已分配四个热带：2v(2)(0) + v(3)
The absorption spectrum of NH2+ has been recorded continuously between 3500 and 2900 cm(-1) with a difference frequency laser spectrometer along with the velocity modulation technique. The molecular ions were produced in the positive column of an ac glow discharge with a gas mixture of N-2/H-2/He in a ratio of around 1/1/100 with a total pressure of similar to 7 Torr. In view of the very low harrier to linearity (155 cm(-1)) and the high bending vibrational states involved, the observed spectrum was analyzed using the Hamiltonian for linear molecules. The choice of this model is discussed in relation to the previous experimental results and ab initio calculations. Four hot bands have been assigned: 2v(2)(0) + v(3)
