Abstract: This fourth subvolume presents data on the geometric parameters (internuclear distances, bond angles, dihedral angles of internal rotation etc) of free polyatomic molecules including free radicals and molecular ions. The survey on structure data consists of four subvolumes, each containing the geometric parameters determined in the gas phase either by an analysis of the rotational constants (and sometimes the vibrational constants) obtained from microwave, infrared, Raman, electronic and photoelectron spectroscopy or by an analysis of electron diffraction intensities. Most of the structures listed in the tables are for molecules in the electronic ground state, but structures for electronically excited states have also been included as far as they are available. In this fourth subvolume, the structure of molecules containing five to sixty carbon atoms is listed.

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.

Abstract: Some years after the publication of Vol. III/11 and its supplement III/18 dealing with elastic, piezoelectric, pyroelectric and optical properties of crystals, a complete recompilation of the data of these volumes and of new data was performed. Because of the growth of this subject matter it was found convenient to divide the material into four volumes, III/29a and b for the low frequency properties and III/30a and b for high frequency propertiesof dielectric crystals. The first subvolume III/29a contains exclusively second and higher order elastic constants including temperature and pressure coefficients.

Because of the growth of this subject matter it was found convenient to divide the material into four volumes, III/29a and b for the low frequency properties and III/30a and b for high frequency propertiesof dielectric crystals. The present second subvolume III/29b essentially contains relative dielectric constants and piezoelectric constants and their temperature coefficients, as well as electrostrictive and pyroelectric coefficients and electromechanical coupling factors of dielectric crystals.

Abstract: While vols. III/29 A, B (published in 1992 and 1993, respectively) contains the low frequency properties of dielectric crystals, in vol. III/30 the high frequency or optical properties are compiled. While the first subvolume 30 A contains piezooptic and elastooptic constants, linear and quadratic electrooptic constants and their temperature coefficients, and relevant refractive indices, the present subvolume 30 B covers second and third order nonlinear optical susceptibilities. For the reader's convenience an alphabetical formula index and an alphabetical index of chemical, mineralogical and technical names for all substances of volumes 29 A, B and 30 A, B are included.

RefComment: Written for Science and engineers in the fields of physics, chemistry and physical chemistry who inted to use NMR to study the structure and the binding of molecules
Abstract: Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, orient by a magnetic field, and absorb characteristic frequencies in the radiofrequency part of the spectrum. The spectral lines of the nuclei are highly influenced by the chemical environment i.e. the structure and interaction of the molecules. NMR is now the leading technique and a powerful tool for the investigation of the structure and interaction of molecules. The present Landolt-Börnstein volume III/35 Nuclear Magnetic Resonance (NMR) Data is therefore of major interest to all scientists and engineers who intend to use NMR to study the structure and the binding of molecules. Volume III/35 "NMR-Data" is divided into several subvolumes and parts. Subvolume III/35A contains the nuclei 11B and 31P, subvolume III/35B contains the nuclei 19F and 15N, subvolume III/35C contains the nucleus 1H, subvolume III/35D contains the nucleus 13C, subvolume III/35E contains the nucleus 17O, and subvolume III/35G contains the nucleus 77Se. More nuclei will be presented later.

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.
