固体对氢是一种很好的基质隔离光谱材料。首先，光谱分辨率超过了常规矩阵的分辨率，因此在有利的情况下，可以对固相分子的转动结构进行详细的分析。其次，原位光解是可行的，这是因为笼子效应在固体对氢气中的消减，这与稀有气体基质中的体系形成了鲜明的对比。在本文中，我们描述了1)固体仲氢作为基质的相关性质，2)使用固体仲氢作为基质的实验程序概述，3)高分辨率光谱研究的例子，以及4)光化学和低温化学研究的例子。
Solid parahydrogen is an excellent matrix for matrix-isolation spectroscopy. First, spectroscopic resolution exceeds the resolution attainable in conventional matrices so that detailed analysis of rotational structure of molecules in the solid phase may be performed in favorable cases. Secondly, in situ photolysis is feasible on account of the subduction of the cage effect in solid parahydrogen, which is in sharp contrast to the system in rare gas matrices. In this Account we describe 1) relevant properties of solid parahydrogen in connection with its use as the matrix, 2) outlines of experimental procedures using solid parahydrogen as the matrix, 3) examples of high-resolution spectroscopic studies, and 4) examples of studies on photochemistry and cryochemistry.
