It follows the same basic concepts, i.e., it provides a representative, albeit limited set of reference data for the interpretation of 13C NMR, 1H NMR, IR, mass, and UV/Vis spectra. We also added a new chapter with reference data for 19F and31P NMR spectroscopy and, in the chapter on infrared spectroscopy, we newly refer to important Raman bands.
