三原子分子振转谱的幺正对称性

Unitary Symmetry of the Triatomic Molecular Spectra

线性三原子分子结构存在着幺正对称性，计算结果表明它们振转谱的对称性能用Ｕ（５）群代数很好描述．

The structure of linear triatomic molecule have unitary symmetry.The calculated result shows that the symmetry of ratation vibrational spectra for linear triatomic molecule can be described by the algebra of U(5) quite well.
