在沃森哈密顿量中的振动角动量项通常被认为是可以忽略的，或者被近似为有效惯性矩张量的倒数的展开的零阶项。用多模展开的方法研究了一阶和二阶项对N（2）H（2）和HBeH（2）BeH振动跃迁的影响.提供了与实验数据的比较。张量的展开可以用来引入有效的预筛选技术。
Vibrational angular momentum terms within the Watson Hamiltonian are often considered negligible or are approximated by the zeroth order term of an expansion of the inverse of the effective moment of inertia tensor. A multimode expansion of this tensor up to second order has been used to study the impact of first and second order terms on the vibrational transitions of N(2)H(2) and HBeH(2)BeH. Comparison with experimental data is provided. The expansion of the tensor can be exploited to introduce efficient prescreening techniques.
