Abstract: The volume II/27 has been divided into three subvolumes according to the classes of compounds: Subvolume A: Diamagnetic susceptibility and magnetic anisotropy of inorganic and organometallic compounds; Subvolume B: Diamagnetic susceptibility of organic compounds, oils, paraffins and polyethylenes; Subvolume C: Diamagnetic susceptibility and magnetic anisotropy of organic compounds. The data presented in this volume are based on the literature survey of the chemical abstracts up to 2005. The calculated values of diamagnetic susceptibility of organic compounds in the present subvolume II/27B are presented along with their experimental values. They have been calculated with the use of structural parameters in structural formula by using different theoretical methods available in the literature.

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.
