在双原子分子气体比热的理论中，函数起着众所周知的重要作用。双原子分子的转动比热Crot可以表示为具有两个相等的主惯性矩的刚体，而不绕另一个主轴旋转，由下式给出：其中R是克分子气体常数，一对相等的惯性矩等于A。这种模型是否是一个适当的代表是一个问题，通过详细研究能带光谱的结构，特别是正常的电子和振动状态的性质来确定。已知它适用于卤素原子的正常分子，适用于CO和具有1S型正常状态的其他分子，包括（但对于某些特殊特征）H2。
In the theory of the specific heats of gases of diatomic molecules the function plays a well-known and important part. The rotational specific heat Crot of a diatomic molecule, which is susceptible of representation as a rigid body with two equal principal moments of inertia, without spin about the other principal axis, is given by where R is the gram-molecular gas-constant and the pair of equal moments of inertia being equal to A. Whether such a model is or is not an adequate representation is a matter for determination by a detailed study of the structure of the band spectrum, particularly of the nature of the normal electronic and vibrational state. It is known to be applicable to normal molecules of the halogen hydrides, to CO and other molecules which have a normal state of type 1S including (but for a certain special feature) H2.
