The use of IR spectroscopy for the evaluation of the Lewis and Bronsted acidity of microporous systems is illustrated having recourse to examples concerning zeolites, heteropolyacids and sulfonated membranes (NAFION). Methods based on the perturbation of the OH modes by interaction with basic probe molecules are illustrated as well as on the perturbation of the internal modes of the probe itself. The use of H2 as probe is also debated by discussing new data specifically obtained for this review. The illustrated case examples are mainly obtained from the experience gained by the Turin group in 20 years.
借助有关沸石、杂多酸和磺化膜（全氟磺酸离子交换膜）的实例，阐述了利用红外光谱法评估微孔体系的路易斯酸度和布朗斯特酸度。文中不仅阐述了基于与碱性探针分子相互作用对OH模式进行扰动的方法，还介绍了基于对探针自身内部模式进行扰动的方法。通过讨论专门为本综述获取的新数据，也对使用H₂作为探针进行了探讨。文中所举的实例主要来自都灵团队20年来积累的经验。
