Abstract: Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. Volume II/24 is a supplement to volumes II/4, II/6, II/14, and II/19 and is planned to appear in five subvolumes, the last of which will contain the substance index taking into account all molecules worked at since 1967 in the volumes mentioned and will provide cross references to and between all tables of these. The present subvolume II/24B contains an introduction and tables of rotational and centrifugal distortion constants of asymmetric-top molecules, i.e. data which roughly specifies the frequencies of the rotational transitions of these types of rotors.

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: Volume III/31 continues the compilation of nuclear quadrupole resonance spectroscopy data of solid substances which started in with volume III/20 in 1987 covering the literature from the beginning of nuclear quadrupole resonance spectroscopy in 1951 to 1982 and containing the data for 8000 substances in the solid state, distributed among three subvolumes III/20 a, b, and c. Volume III/31 covers the literature published in the period from the end of 1982 through the end of 1989. Included are the data for substances studied for the first time, as well as data for substances already present in the previous volume III/20 if the data published there could be completed or improved by new studies. In total there are 2500 substances in volume III/31, showing the scope and significance of nuclear quadrupole resonance spectroscopy up to recent times.

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. NMR is now a 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 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 B-11 and P-31, subvolume III/35B contains the nuclei F-19 and N-15, subvolume III/35C contains the nucleus H-1, subvolume III/35D contains the nucleus C-13, subvolume III/35E contains the nucleus O-17, and subvolume III/35G contains the nucleus Se-77. More nuclei are planned for future volumes.
