Interatomic Distances of Molecule for Orthohydrogen and Parahydrogen;

正氢和仲氢分子的核间距

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。

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。

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。

Through finishing the study of the change of o-H2 and p-H2 by catalyst, we have eliminated the measurement influence of chromatograph quantitative analysis on depleted deuterium.

在完成了正仲氢转化对贫氘氢(氘丰度小于10-5)色谱TCD定量分析影响的研究后,运用反峰色谱原理,确定了D/H的在线色谱定量分析方法,可在线检测氘丰度小于10-5的样品。

If our assumption about the probability factor is correct, this means that Eact is less for abstraction of a secondary hydrogen than for abstraction of a primary hydrogen.

假如我们对几率因子的推测是正确的，这就意味着夺取仲氢的E活化比夺取伯氢的E活化
