This review addresses the most relevant aspects of vibrational spectroscopies (IR, Raman and INS) applied to zeolites and zeotype materials. Surface Brønsted and Lewis acidity and surface basicity are treated in detail. The role of probe molecules and the relevance of tuning both the proton affinity and the steric hindrance of the probe to fully understand and map the complex site population present inside microporous materials are critically discussed. A detailed description of the methods needed to precisely determine the IR absorption coefficients is given, making IR a quantitative technique. The thermodynamic parameters of the adsorption process that can be extracted from a variable-temperature IR study are described. Finally, cutting-edge space- and time-resolved experiments are reviewed. All aspects are discussed by reporting relevant examples. When available, the theoretical literature related to the reviewed experimental results is reported to support the interpretation of the vibrational spectra on an atomic level.
这篇综述讨论了应用于沸石和类沸石材料的振动光谱（IR、拉曼和 INS）的最相关方面。详细讨论了表面 Brønsted 和 Lewis 酸和表面碱性。还批判性地讨论了探针分子的作用以及调整探针的质子亲和性和空间位阻以充分理解和绘制微孔材料内复杂的位点分布的相关性。详细描述了精确确定 IR 吸收系数所需的方法，使 IR 成为一种定量技术。从变温 IR 研究中可以提取出吸附过程的热力学参数。最后，综述了前沿的空间和时间分辨实验。通过报告相关示例讨论了所有方面。在有可用的理论文献时，报告了与所综述的实验结果相关的理论文献，以支持在原子水平上对振动光谱的解释。
