Abstract: Volume II/25 is a supplemented and revised edition of the preceding volumes II/7, II/15, II/21 and II/23 containing up to date information on inorganic and organic polyatomic molecules. All experimental methods for the determination of quantitative structural data of free molecules have been considered: microwave, infrared, Raman, electronic and photoelectron spectroscopy as well as electron diffraction. The data obtained by these methods have been critically evaluated and compiled. They are presented separately for each molecule, together with a schematic figure of the structure and the original literature.

Abstract: This volume is a compilation of vapor–liquid equilibrium data on subcritical binary single-phase or two-phase liquid–liquid systems. All the components are well-defined pure substances, which are organic or inorganic nonelectrolytes, including low-melting ionic liquids and water. The present database contains numerical data for 3316 systems. The book reproduces in tables and graphs the numerical values for only 802 binary mixtures, chosen to be representative of all the compound classes and property types. The full set of data is given on the CD–ROM accompanying the book. Most data files contain experimental data compiled from the original literature published from 1929 to mid 2006. The CD-ROM displays all these data in PDF format and in fully documented computer readable standard electronic files (SELF and ELDATA). The ELBT-program allows the fast search of data according to property type, chemical system, author(s), source and year of publication. It also includes the bibliographical database of ELDATA, EVLM’2006, giving 13471 references from 1888 through mid 2006 to experimental vapor–liquid equilibrium in mixtures and solution.

Abstract: Diffusion – defined as mass, amount, or particle transport process – is the most essential transport property besides viscosity and thermal conductivity. Diffusion is widely used in nature, technical and scientific applications, ranging from diffusion in all kinds of gases, liquids, solids, electrolytes and their mixtures. Due to the large amount of data, the volume LB IV/15 "Diffusion in Gases, Liquids, and Electrolytes" is divided into three subvolumes. Part A: Gases in Gases, Liquids and their Mixtures; Part B: Liquids in Liquids and Liquid Mixtures; Part C: Ions and Electrolytes in Liquids, Electrolytes and Molten Salts. The presented subvolume A includes the main chapters Measurement Methods, Diffusion in Pure Gases, Diffusion in Gaseous Mixtures, Diffusion of Gas/Vapor in Gases or Liquids and Diffusion of Gases in Solution. Due to the very different and widespread measurement methods, a precise description of these methods is given.

Abstract: Critically evaluated experimental data covering the densities of organic compounds are essential for both scientific and industrial applications. Knowledge of densities is important in many areas, including custody transfer of materials, product specification, development of various predictive methods, and for characterizing compounds and estimating their purity. This volume contains tables with the original literature data along with their estimated uncertainties and the evaluated data in both numerical form and as coefficients to equations with selected statistical information. When data cover a sufficient temperature range, graphical plots of the deviations of the experimental data from the recommended equation are given. A Chemical Name Index contains the IUPAC names for the compounds, as well as alternate names that often appear in practice. Also includes a Chemical Abstracts Service Registry Number Index and a list of References.
