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.

Abstract: Vols. III/17a-i and III/22a, b (supplement) on semiconductor physics and technology have been published earlier, the latter covering new data on the technologically important group IV elements and III-V, II-VI and I-VII compounds only. The wealth of further data from the last decade is now being critically evaluated by over 30 well-known experts in the field of semiconductors. To meet the demands of todays scientists and to offer a complete overview on semiconductor data all data available so far are published in the following way: a series of five subvolumes covers only the supplementary data to volumes III/17 and 22.
