Editor: Gupta, R.R.; Lechner, M.D. Source: Landolt-Börnstein, New Series Volume: III/35E Year: 2002 Keyword: Alipathic and Aromatic hydrocarbons; Coupling constant j; Nuclear Magnetic Resonance; chemical shifts δ ISBN: 3-540-42501-2 ISBN: 978-3-540-42501-4 Internet Resource: DOI:10.1007/b92953 RefComment: VII, 230 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), carbon-13 (subvol. D), and oxygen-17 (subvol. E) 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.

Source: Landolt-Börnstein, New Series Volume: IV/1a Year: 1974 ISBN: 3-540-06269-6 ISBN: 978-3-540-06269-1 Internet Resource: DOI:10.1007/b20003 RefComment: X, 716 pages. 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.
