由于 Q3(0) ~v53←0、J50←0 的本地化增强和长寿命！激发时，观察到一系列 17 个尖锐的光谱特征，并完全归因于正氢/仲氢对的特定量子态之间的跃迁。在 11 758 和 11 759 cm 之间的高分辨率下观察到，十个最强的特征是由于 J50 H2 和 J51 H2 的晶体最近邻对分别正在经历和诱导转变，而另外七个特征则来自次近邻对和更远的邻居相互作用。这项研究直接测量了纯对氢晶体中 J51 H2 的晶体场分裂。测得的晶体场分裂 D 5E(M561)2E(M50) 为 0.007160.0002 cm。还直接观察和分析了激发态晶体场和对分裂。 @S0163-1829~98!05301-6#
Due to the increased localization and long lifetime of the Q3(0) ~v53←0, J50←0! excitation, a series of 17 sharp spectral features has been observed and completely assigned to transitions between specific quantum states of the orthohydrogen/parahydrogen pair. Observed under high resolution between 11 758 and 11 759 cm, the ten strongest features are due to crystalline nearest-neighbor pairs of J50 H2 and J51 H2 that are undergoing and inducing the transition, respectively, while seven additional features arise from nextnearest-neighbor pairs and farther away neighbor interactions. This study gives a direct measurement of the crystal-field splitting for J51 H2 in otherwise pure para-H2 crystals. The measured crystal-field splitting, D 5E(M561)2E(M50), is 0.007160.0002 cm. The excited-state crystalline-field and pair splittings are also directly observed and analyzed. @S0163-1829~98!05301-6#
