• Short: III/35B Title: Nuclear Magnetic Resonance (NMR) Data: Chemical Shifts and Coupling Constants for Fluorine-19 and Nitrogen-15 Author: Balasubramanian, M.; Gupta, R.R.; Jain, M.; Perumal, S. Editor: Gupta, R.R.; Lechner, M.D. Source: Landolt-Börnstein, New Series Volume: III/35B Year: 1998 ISBN: 3-540-63275-1 ISBN: 978-3-540-63275-7 Internet Resource: DOI:10.1007/b55685 RefComment: VII, 242 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 CO-ROM's.

NMR is now a leading technique and a
