尽管与经典分光光度法相比，现代 NMR 的时间分辨率较差且灵敏度较低，但现代 NMR 现已成为一种高度发达的光谱技术，由于其高光谱分辨率和可提供详细结构和定量信息的二维 (2D) NMR 技术，适用于光致变色研究。因此，核磁共振波谱可用于回答有关产生哪些化合物、它们如何形成以及它们在光致变色反应中如何演变和表现的问题。在这篇综述中，我们选择了各种各样的光致变色分子，螺环化合物、萘并吡喃、二氢芘、二芳基乙烯和芳基二酮家族中的一些具体例子来说明核磁共振在光致变色动力学和结构研究中的作用。
Despite its poor time-resolution and low sensitivity compared with classical spectrophotometric methods, modern NMR is now a highly developed spectroscopy technique, appropriate for photochromism studies owing to its high spectral resolution and two-dimensional (2D) NMR techniques that offer detailed structural and quantitative information. NMR spectroscopy can therefore be applied to answer questions concerning which compounds are produced, how they are formed and how they evolve and behave within the photochromic reaction. In this review, we have chosen among the wide variety of photochromic molecules, some specific examples in the family of spirocompounds, naphthopyrans, dihydropyrenes, diarylethenes and aryldiketones to illustrate the ways in which NMR has proved useful in the kinetic and structural studies of photochromism.
