With CD-ROM., Hardcover RefComment: Written for scienctists and engineers in the fields of physics, chemistry and physical chemistry who inted to use NMR to study the structure and the binding of molecules Abstract: NMR is now the leading technique and a powerful tool for the investigation of the structure and interaction of molecules. The present Landolt-Börnstein vol.III/35 "Nuclear Magnetic Resonance (NMR) Data" is therefore of major interest to all scientists and engineers who intend to use NMR to study the structure and the binding of molecules. Vol. III/35 "NMR-DATA" is divided into several subvol.and parts. III/35 A contains the nuclei 11B and 31 P, III/35 B contains the nuclei 19F and 15 N, III/35 C contains the nucleus 1H, III/35 D contains the nucleus 13C, III/35 E contains the nucleus 17O, and subvolume III/35G contains the nucleus 77Se.

Hardcover 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.
