Hardcover Abstract: For more than 1000 luminescent organic substances the most important data are represented as wave numbers of absorption and emission bands, decay times and quantum efficiencies. Additional tables contain further information for restricted groups of substances (figures on typical spectra, wave numbers of sharp single bands, influence of surrounding molecules, etc.).

Hardcover Abstract: Nuclear Quadrupole Resonance Spectroscopy has become a standard method for structural research in molecular and solid state physics as well as for different branches of chemistry. The volumes cover data for more than 8,000 substances in the solid state. Data for free molecules have been published in volumes II/14 and II/15 of the New Series. The tables are arranged according to the atomic number of the elements.
