分子的能级 meaning in English

molecular energy level

Triatomic and larger molecules have more complex energy-level diagrams .
三原子分子和更大的分子的能级图比较复杂。
To describe the experiments and to study the intensities of all kinds of transitions , from 1980s , wulfman , levine , lachello and oss tried a new method and proposed the algebraic model of molecules , i . e . , to calculate the spectroscopy of molecules by algebraic method . by making use of the algebraic model , we got precise results with less parameters . but it became very difficult to calculate anything as the overtone v increased , for they were done in a non - symmetry adapted bases
Wulfman , levine , iachello和oss从80年代开始致力于新方法的研究，提出了分子的代数模型，即用代数的方法来研究分子的能级和跃迁强度，这种方法不仅所需要的参数较少而且得到的结果比较精确，但是由于采用的是非对称局域基，所以对于振动量子数很大的振动来说计算量很大。
