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...

Thermodynamics determines the properties and region of existence of any alloy. Pressure, temperature and composition are the key parameters that dictate its crystal structure, crystallographic data, physical and mechanical properties. Phase diagrams are of utmost importance as overviews of the particularities of any alloying mixture. The present volume presents phase equilibria, thermodynamic and crystallographic data of the binary alloys K-O ... Y-Zr.

The development and research of all kinds of optical applications and instruments require the knowledge of basic optical properties. The present volumes comprises data on optical constants of non-electrolyte systems, comprising pure liquids and binary liquid mixtures at normal pressure.The data contain refractive indices as a function of temperature, wavelength 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...

The present subvolume provides evaluated data from HD16O, HT16O, HD17O, HD18O, and DT16O isotopologues. The introduction is intended to give a quicker access to the meanings of symbols found in the data tables. It reports molecular theories and equations, based on which most of the evaluated data given in the tables are established. These tables are preceded by an additional index in order to facilitate the search for specific information.
The tables report molecular constants and/or, below about 5000 cm 1, assigned...
