The collection contains 2,900 polymer spectra with extensive sample information. All spectra are high quality FT-IR spectra at a resolution of 2 cm-1 (data point distance 1 cm-1). Associated legends quote references, inform about the origin and the synthesis of the polymers as well as the sample preparation. Each compound is identified by its IUPAC or common names. Available database formats: Galactic; Bruker; Shimadzu; Nicolet; ACD; Perkin Elmer; Mattson; Lumex; SpecTacle
