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 ).
