本文综述了准完美 Pt(111) 单晶水电解质界面的原位光谱学领域。提供了同时应用差示反射光谱和二次谐波产生作为离子和分子吸附物的静态和动态探针的插图。人们的注意力集中在硫酸氢盐吸附的定量研究以及一氧化碳吸附层的相变动力学和反应性及其对施加电势的依赖性。还讨论了这些技术当前的局限性，以及提高其时间和空间分辨率的可能方法。
The area of in situ spectroscopy at quasi-perfect Pt(111) single-crystal facet|aqueous electrolyte interfaces is herein reviewed. Illustrations are provided of the simultaneous application of differential reflectance spectroscopy and second-harmonic generation as static and dynamic probes of ionic and molecular adsorbates. Attention is focused on quantitative studies of bisulfate adsorption as well as of the dynamics of phase transitions and reactivity of carbon monoxide adlayers and their dependence on the applied potential. Also discussed are current limitations of these techniques, as well as possible means to improve their temporal and spatial resolution.
