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.
