Organic and hybrid thin film materials are of high relevance in many fields of optics, electronics, and biomedicine. An IR spectroscopic study of manipulations of characteristic vibrational bands is presented by Karsten Hinrichs et al. (article number 1900490). In the p‐polarized IR reflection of a polyimide film, band manipulations related to electric fields and anisotropic absorption indices are identified. Differences of s‐ and p‐polarized AFM‐IR spectra reveal a corresponding manipulation of the absorption by the incident radiation‐induced electric fields in direction normal to the surface. In contrast, the s‐polarized reflection exhibits material specific fingerprints, and spectra resemble the in‐plane absorption properties of the material. – The cover article belongs to a special section on “Optics of Surfaces and Interfaces” in this issue, comprising 7 Original Papers and guest‐edited by Bernardo Mendoza, Ramón Carriles, and Sean Anderson (see Editorial, article number 2000215).

薄膜中红外吸收特性的场操纵

有机和混合薄膜材料在光学，电子学和生物医学的许多领域具有高度相关性。Karsten Hinrichs等人提出了对特征振动带进行操纵的红外光谱研究。（商品号1900490）。在聚酰亚胺薄膜的p偏振IR反射中，可以识别出与电场和各向异性吸收指数有关的能带操作。s极化和p极化的AFM-IR光谱的差异揭示了入射辐射诱发的电场在垂直于表面方向上对吸收的相应控制。相反，s偏振反射显示出特定于材料的指纹，并且光谱类似于材料的面内吸收特性。–封面文章属于本期“表面和界面的光学”的特殊部分，
