Surface tension of liquids determine fundamental chemical and physical properties and applications. Cleansing agents, soldering agents, pharmalogical substances and biomechanical phenomena all rely on surface tensions and their deliberate modifications, so that a collection of reliable data will be of interest for users in science, research and engineering.

This supplement volume contains surface tensions of non-electrolyte material systems, as well as surface tensions data of pure liquids and binary liquid mixtures at normal temperatures.

This volume includes 19 contributions to the 13th International Symposium on Analytical Ultracentrifugation which took place at the university of Osnabruck on March 6th and 7th, 2003. The contributions from leading scientists cover a broad spectrum of topics concerning: Technical Methods, Data Analysis, Innovations; Polymers, Colloids, Supramolecular Systems; Biological and Interaction Systems; Hydrodynamics and Modelling.

Due to the increasing significance of Analytical Ultracentrifugation for both scientific and technical applications, this book will be an essential...

The porphyrins are an important class of naturally occurring macrocyclic 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...

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.

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. NMR is now the leading technique and a powerful tool for the investigation of the structure and interaction of molecules. The present Landolt-Bornstein volume III/35 "Nuclear Magnetic Resonance (NMR) Data" is therefore of major interest to all...
