方位角(α,β,γ)能确定刚性分子的自由度吗?

Can the azimuths (α,β,γ) identify the rotational degree of freedom for a rigid diatomic molecule?

指出了大学物理教材中刚性双原子分子的转动自由度的个数不能用通常的方位角（α，β，γ）来确定，而用球坐标系可以准确地说明这一问题．

This article points out that in the university physics the number of the rotational degree of freedom for a rigid diatomic molecule cannot be identified by the azimuths （α,β,γ）, but this problem can be indicated precisely with the spherical coordinates.
