Polymers belong to an essential material group with many applications not only for polymer manufacturers but also in physics, chemistry, medicine and engineering techniques. The presented volume is the third part of a book series connecting a complete data collection with short but precise descriptions of the different quantities and their significances. The experimental determination of the physical quantities is given as well as the influence to other physical quantities. This volume helps to choose the best material for all kinds of applications also for those which are not mentioned in...

The magnetic properties of silicates and phosphates are compiled in subvolume 27I. While subvolumes 27I1, 27I2, 27I3, 27I4, and 27I5 (already published) deal with orthosilicates, sorosilicates, cyclosilicates, inosilicates, and phyllosilicates, respectively, the present subvolume 27I6 deals with tectosilicates. Subvolume 27I6 has been split in three parts α, and γ. Further subvolumes will be dedicated to phosphates. - Silicates are very complex systems, covering large classes of minerals as well as synthetic samples. Their crystal structure is discussed and atomic positions are...

With the development of modern instruments and theories, a considerable amount of spectroscopic informationis being permanently collected on molecules. The infrared, in particular, is seeing extraordinary activities. Using Fourier transform interferometers and infrared lasers, accurate data are measured often with extreme sensitivity. These data are also analyzed and precise molecular parameters determined. Volume II/20, "Molecular Constants Mostly from Infrared Spectroscopy," is a recent Landolt-Bornstein publication series bringing together these results. It is made up of several volumes...

This index is a guide to organic compounds which have material constants of general interest described in the Landolt-Bornstein / New Series.In total in the subvolumes J, K, L and M, 23865 compounds with 83941 references to numerical data are recorded Compiled are volumes containing nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) data, acoustical and optical properties, structure and molecular constants, mechanical and thermodynamic constants as well as physical properties of liquid crystals. All new compounds are given with the drawing of the chemical structure,...

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 for daily life. Consequently, there are many research activities dealing with zeolite properties and...

After a historical consideration of the types and evolution of accelerators the physics of particle beams is provided in detail. Topics dealt with comprise linear and nonlinear beam dynamics, collective phenomena in beams, and interactions of beams with the surroundings. The design and principles of synchrotrons, circular and linear colliders, and of linear accelerators are discussed next. Also technological aspects of accelerators (magnets, RF cavities, cryogenics, power supply, vacuum, beam instrumentation, injection and extraction) are reviewed, as well as accelerator operation...

The Landolt-Bornstein volume II/30 contains 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. This volume is made of two 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. All data obtained...
