在过去的30年里，单晶光晶体技术已经发展到可以确定晶体光化学产生的亚稳态物质的三维晶体和分子结构。使用这种方法研究的过渡金属配合物包括含有亚硝酰基、二氮、二氧化硫和亚硝酸盐配体的配合物，所有这些配合物在被适当波长的光光活化时在固态下形成新的连接异构体。空间因素和电子因素都决定了从基态结构到亚稳态异构结构的转化水平，并且“反应腔”大小和分子间相互作用的性质被证明是影响转化百分比的关键因素。
Over the last 30 years, the single-crystal photocrystallographic technique has been developed to determine the three-dimensional crystal and molecular structures of metastable species which have been generated in the crystal photochemically. Transition-metal complexes that have been investigated using this methodology include complexes that contain nitrosyl, dinitrogen, sulfur dioxide and nitrite ligands, all of which form new linkage isomers in the solid state when photoactivated by light of the appropriate wavelength. Both steric and electronic factors determine the level of the conversion from the ground-state structure to the metastable isomeric structure, and both the 'reaction cavity' size and the nature of the intermolecular interactions are shown to be among the key factors that influence the percentage conversion.
