• Short: II/22b Title: Theoretical Structures of Molecules: Small Rings Author: Hampel, F. Editor: von Ragué Schleyer, P. Source: Landolt-Börnstein, New Series Volume: II/22b Year: 1994 ISBN: 3-540-56332-6 ISBN: 978-3-540-56332-7 Internet Resource: DOI:10.1007/b48044 RefComment: VIII, 160 pages. Hardcover Abstract: Volume II/22 presents computed geometries. Quantum chemical computations provide an excellent alternative to experimental methods for the determination of accurate structures of polyatomic molecules. The objective is not to duplicate, but rather to complement the existing literature. An advantage of computational chemistry over experimental methods is the possi-bility to obtain reliable geometries of molecules, even of important systems, which are difficult to synthesize, isolate, and to study experimentally.
• Short: III/35C4 Title: Nuclear Magnetic Resonance (NMR) Data: Chemical Shifts and Coupling Constants for Hydrogen-1, Part 4: Inorganic and Organometallic Compounds Author: Gupta, R.R.; Platzer, N. Editor: Gupta, R.R.; Lechner, M.D. Source: Landolt-Börnstein, New Series Volume: III/35C4 Year: 2001 Keyword: Hydrogen 1; Nuclear Magnetic Resonance ISBN: 3-540-41059-7 ISBN: 978-3-540-41059-1 Internet Resource: DOI:10.1007/b76570 RefComment: VII, 299 pages. With CD-ROM. Hardcover Abstract: This volume provides a comprehensive and evaluated compilation of nuclear magnetic resonance data. Chemical shifts and coupling constants of boron-11 and phosphorus-31 (subvol. A), fluorine-19 and nitrogen-15 (subvol. B), hydrogen-1 (subvol. C), and carbon-13 (subvol. D) compounds are tabulated together with the gross- and structure formulas and the most readily available solvents. Due to the large amount of the data merely chemical shifts are presented in the printed versions, and all the data, chemical shifts and coupling constants are provided on CD-ROM's.
