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: Volume IV/1 contains information on the densities of liquid systems. It may be considered as a supplement to volume II/1 of the 6th Edition, which contains only a few data on nonaqueous systems. Data are not listed for all systems but primarily for those of greater interest where data for a larger range of concentrations were available.
