在考虑（310），（211），（112），（013），（230），（131）和（032）七个态之间共振相互作用的哈密顿模型框架下，分析了D20（ν = ν1 + ν2/2 + ν3 = 3.5）多原子态的高分辨傅里叶变换光谱.在实验记录的光谱中，归属了属于2ν1 + ν2 + ν3，3ν1 +ν2和3ν2 + 2ν3带的跃迁。这提供了获得“可见”态（211）、（310）和（032）的光谱参数和估计“暗”态（112）和（131）的带中心以及旋转和共振相互作用参数的可能性。
The high resolution Fourier transform spectrum of the D20 (ν = ν1 + ν2/2 + ν3 = 3.5) polyad was analysed within the framework of the Hamiltonian model taking into account resonance interactions between the seven states (310), (211), (112), (013), (230), (131) and (032). Transitions belonging to the 2ν1 + ν2 + ν3, 3ν1 +ν2 and 3ν2 + 2ν3 bands were assigned in the experimentally recorded spectrum. This provided the possibility of obtaining spectroscopic parameters of the ‘visible’ states (211), (310) and (032) and of estimating the band centres, and the rotational and resonance interaction parameters of the ‘dark’ states (112) and (131).
