结果表明，对称陀螺分子的转动能级可以根据分子全对称群的对称种类进行分类。有用的选择规则，从而分类的旋转能级之间的电偶极跃迁。结果表明，转动能级可以另外用一个方便的量子数G来标记，它本质上是+1，-1标记的推广.这个量子数的选择规则，其中，连同那些对称物种，允许一个容易地确定允许的分支之间的任何两个振动态之间的过渡对称顶部分子。
It is shown that the rotational energy levels of a symmetric‐top molecule can be classified according to symmetry species of the full symmetry group of the molecule. Useful selection rules for electric‐dipole transitions between rotational energy levels thus classified are presented. It is shown that the rotational energy levels can be labeled in addition by a convenient quantum number G, which is essentially a generalization of the +l, —l labels. Selection rules for this quantum number are presented, which, together with those for the symmetry species, allow one to determine easily the allowed branches for a transition between any two vibronic states in a symmetric‐top molecule.
