Free radicals, which are key intermediates in many thermal, photochemical and radiation processes, are important for a proper understanding of fundamental natural processes and the successful development of organic syntheses. V"olume " "II/18" serves as a supplement and extension to "volume II/13" and covers rate constants and other kinetic data of free radical reactions in liquids. "Furthermore II/18" contains new chapters on reactions of radicals in excited states and of carbenes, nitrenes and analogues. Selected species in aqueous solutions for which other compilations are available were...

Astronomy and Astrophysics were first treated in volume III of the 6th edition of Landolt-Bornstein in 1952, then in volumes VI/1 and VI/2 of the New Series, 1965 and 1981/82 respectively. The present volume VI/3 is a further supplementation of volume VI/1. The decimal classification scheme of the first supplement volumes, VI/2, has been maintained, fields without significant new developments are clearly indicated. A synoptic list of contents over all three volumes provides an excellent overview for the user as well as a Comprehensive Index in the forthcoming last subvolume of VI/3.

For everyone concerned with the technology and application of metals and alloys and with the development of new metallic materials, a detailed knowledge of phase equilibria is indispensable. Also, information on the thermodynamical and crystallographical data of the systems under investigation is essential, and often metastable crystalline phases as well as quasicrystalline or amorphous alloys are of interest. Vol. IV/5 presents all these data. Because of the large amount available of experimental evidence and thermochemical calculations, a presentation in one volume, as it was...

This series of Landolt-Bornstein volumes is summarizing our current knowledge of the phenomena of mesoscopic quantum systems with spatial extensions between those of atoms and ordinary macroscopic solids. At low temperatures, they are said to become "quantum mechanically coherent" with states that extend over the whole system."

Zeolites and zeolite-like materials became important because of their ion exchange capacities and their outstanding catalytic properties. Millions of tons of zeolites have been produced in the past years for the oil refining industry alone and, in even greater quantities, as ion-exchanging softening agents for detergents. Numerous other applications, e.g. in environmental protection, farming, gas separation, medicine, and pharmacy, are known, making zeolites almost a necessity of daily life. Consequently, there are many research activities dealing with zeolites properties and...

Volume III/39 contines the compilation of nuclear quadrupole resonance spectroscopy data of solid substances which started with volumes III/20 and III/31. The literature from the beginning of nuclear quadrupole resonance spectroscopy in 1951 to 1996 is covered. Included are the data for substances studies for the first time, as well as data for substances already present in the previous volumes, if the data published there could be completed or improved by new studies. In total there are more than 10,000 substances in the volumes, showing the scope and significance of nuclear quadrupole...

Volume II/20 provides critically evaluated data on free molecules, obtained from infrared spectroscopy and related experimental and theoretical investigations.
The volume is divided into four subvolumes, "A: Diatomic " "Molecules," "B: Linear Triatomic Molecules," "C: Nonlinear " "Triatomic Molecules," "D: Polyatomic Molecules."
Subvolume B2 contains data for CO2 (OCO) and has been split into two parts. Subvolume II/20 B2 has dealt exclusively with the normal isotopic species of carbon dioxide 12C16O16O. The present part ss deals with thirteen isotopic varieties of CO2. Subvolume B3...

Data on ferroelectric and antiferroelectric behaviour of pure compounds and solid solutions are critically evaluated and in addition all other properties relevant to the characterization of these crystals are presented in tables and figures. Subvolume A is for oxides and B for non-oxides including liquid crystals. This subvolume consists of a printed version and an electronic version on CD-ROM. All the compiled data can be found on the CD-ROM. The abundance and diversity of the data, however, make an overview of the relevant research field difficult, and thus the printed version is designed...
