This volume contains selected presentations from the 17th European Symposium on Polymer Spectroscopy (ESOPS17). The biennial series of ESOPS meetings brings together scientists specialized in various spectroscopic methods, from both academic institutions and industry. They discussed the latest developments in the spectroscopic characterization of polymeric materials. Methods, like infrared and Raman spectroscopy and imaging, NMR and ESR spectroscopy, dielectric spectroscopy, also in combination with light and electron microscopy and near-field imaging, are covered.
