This book is based on a number of lectures and posters presented at the 16th European Symposium on Polymer Spectroscopy (ESOPS16) held in Rolduc, Kerkrade, The Netherlands. The articles cover a broad range of spectroscopic techniques applied to wide variety of application areas, such as plastic electronics, biopolymers, interfaces, process analysis, engineering plastics and coatings. In addition, this issue contains contributions discussing novel combinations of techniques developed during the last decade.
