Subvolume D: Chemical Shifts and Coupling Constants for Carbon-13
Inbunden, Engelska, 2010

Skickas inom 10-15 vardagar
The present volume was begun by the late Dr. H.-O. Kalinowski, Justus-Liebig-Universität, Gießen, 13 Germany who could not continue the work on it. His books about the theory and applications of C NMR are well known and helpful to many chemists. The authors and the editors dedicate the volume to the memory of Dr. H.-O. Kalinowski. Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, oriented 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. Magnetic properties of nuclei have been known since 1924 and the first Nuclear Magnetic Resonance experiment was performed in 1945. 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.

Diffusion in Gases, Liquids and Electrolytes
Nonelectrolyte Liquids and Liquid Mixtures - Part 1: Pure Liquids and Solute in Solvent Systems
Inbunden, Engelska, 2017

Skickas inom 10-15 vardagar
This volume contains data on diffusion in pure liquids and solute in solvent systems. Diffusion processes are widespread phenomena in nature, of which mass diffusion is the most important one, in particular in liquids. The corresponding diffusion coefficients strongly depend on concentration, temperature, pressure and density. Contrary to the measurement of viscosity or heat transfer, where a few well developed experimental methods exist, we find a wide spectrum of different methods for measuring mass diffusion coefficients ranging from NMR spectroscopy, scattering, holography, interferometry, chromatography, diffusion through diaphragm and in capillary systems, and electroanalytical methods.After an introduction about the selection and normalization of data, in its first part this volume presents the most important measurement methods, followed by a second part on diffusion coefficient data depending on the various parameters.

1 Introduction Data extract from Landolt-Börnstein IV/17: Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures 1. 1 Selection of data This supplement updates Landolt-Börnstein's New Series Group IV (Physical Chemistry) Volume 6, Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures, published in the year 1991 [1991WOH1]. The update provides experimental data published in the years 1991 to 2006. The ?nal date for including data was December, 31st, 2006. Specialization and selection of data for this new update follows the intentions of the original volume. The focus is on non-electrolyte systems, and only data for pure liquids and binary liquid mixtures at normal pr- sure (or in some single cases at the saturation vapor pressure) were taken into account for this volume. No data at higher pressures were collected, no data for the gaseous state, and no data for dielectric relaxation processes at higher frequencies have been included. For mixtures, this data collection is restricted to binary liquid mixtures, i. e. no ternary systems and also no solutions of any solids, salts, electrolytes, polymers are included here. At least, also molten metals and metallic alloys, molten salts, molten glasses and other hi- temperature melts were not taken into account. As the amount of data collected between 1991 and 2006 exceeds the available space for printing by far, the volume has an electronic version containing additional data which is available on www. landolt-boernstein.

The objective of this volume is to present a full and critical spectral data coverage of the entire major fields relating to porphyrin isomers and expanded porphyrins, their precursors, catabolic derivatives and related systems electronically.The porphyrins are an important class of naturally occurring macro cyclic compounds that play a very important role in the metabolism of living organisms. They have a universal biological distribution and were involved in the oldest metabolic phenomena on earth. Without porphyrins and their relative compounds, life as we know it would be impossible and therefore the knowledge of these systems and their excited states is essential in understanding a wide variety of biological processes, including oxygen binding, electron transfer, catalysis and the initial photochemical step in photosynthesis.
Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures

The storage of electric energy depends on the capacity of the associated electrical components. The material's dielectric constant directly governs this capacity. Dielectric constants therefore gain renewed attention with the increasing need of saving, accumulating and delivering energy produced in the most various ways (wind energy, solar energy, feed-back energy etc.).This supplementary volume contains static dielectric constants as a function of temperature, and - for the binary mixtures - as a function of composition.The focus lies on non-electrolyte systems and pure and binary liquid mixtures at normal pressure.

The present volume comprises data on viscosities of non-electrolyte systems, containing pure organic liquids and binary liquid mixtures at normal pressure.Production, transportation and use of liquid materials directly depend on their physical features, among which their viscosities play a key role.Travelling through a pipe, drying out of a building material, dispensing a fluid into packaging are just few examples of how important reliable data on liquid viscosities are.The data present viscosities as a function of temperature and - for binary mixtures - of composition at normal pressure.

Electrochemistry is the basis of many important and modern applications and scientific developments such as nanoscale machining (fabrication of miniature devices with three dimensional control in the nanometer scale), electrochemistry at the atomic scale, scanning tunneling microscopy, transformation of energy in biological cells, selective electrodes for the determination of ions, and new kinds of electrochemical cells, batteries and fuel cells. In particular the latter point has increased the need for fundamental data of electrochemical systems in recent years, to enable academic and corporate institutions to conduct thorough and forward-thinking research.The present volume IV/9B2 comprises data on the ionic conductance of deep eutectic systems and electrolyte solutions. Definitions and an overview on theory and measurement methods are to be found in the previous volume IV/9B1.
