By using light scattering technique, the transition of rotating energy levels from hydrogen molecular occurs and produced rotating Raman bands for orthohydrogen and parahydrogen are at 587.
采用光散射技术，促使氢分子产生转动跃迁，得到正氢和仲氢的转动拉曼光谱，其峰位为５８７。
3.
Molecular structuxe of normal hydrogen and parahydrogen were discussed.
本文首先对标准氢（Normalhydrogen）及仲氢（Parahydrogeh）的分子结构特性作了论述，然后对它们的热力学性质数据进行了分析研究和计算，并为工程计算提供了一套氢的物性基础数据。
5) para-hydrogen
仲氢
1.
When ortho-hydrogen and para-hydrogen are in exact equilibrium state, the rotational partition function of hydrogen is Z~(r?n)=34Z~(r)_(o)+14Z~(r)_(p),and when hydrogen is non-equilibrium mixture of ortho-hydrogen and para-hydrogen, then the rotational partition function of hydrogen molecule is Z~(r?n)_(混)=Z~(r)_(o)~(N_(o)/N)·(Z~(r)_(p))~(N_(p)/N).
当正氢和仲氢处于完全平衡态时,分子的转动配分函数为Zrn=34Zro+14Zrp;当氢气为正氢和仲氢的非平衡混合物时,分子的转动配分函数为Zrn混=(Zro)No/N(Zrp)Np/N。
