Public ISBD Titre de série : Zahlenwerte und Funktionen aus Physik, Chemie, Astronomie, Geophysik und Technik, 2 / 10 Titre : Magnetic properties, II. Eigenschaften der Materie in ihren Aggregatzuständen. Magnetische Eigenschaften, II Type de document : texte imprimé Auteurs : Hans Heinrich Landolt, Éditeur scientifique ; Richard Börnstein, Éditeur scientifique ; Karl-Heinz Hellwege ; Anne Marie Hellwege Editeur : Berlin, Heidelberg : Springer Verlag Année de publication : 1967 Importance : 173 p. Langues : Allemand (ger) Résumé : Extrait de la préface : "The present Volume II/ 10 completes the compilation given in Volume II/9 pertaining to magnetic data of matter in its various states of aggregation. It contains the magnetic constants of diamagnetic substances and of paramagnetic organic compounds. The free radicals were already covered in Volume II/ 1 of the New Series. As mentioned in the preface to Volume II/9, strict adherence to the guiding principles for the division of the substances was not feasible and therefore some overlapping could not be avoided. For example the diamagnetic semi-conductors were already included in Volume II/9. In order to facilitate comparisons for the user of the new Volume II/ 10, we have listed again the relevant semi-conductors in II/ 10 together with the diamagnetic elements. In the interest of the users such small overlapping seems justifiable. The diamagnetic substances are treated in two tables. In 2 10 1 the diamagnetic susceptibilities are compiled, and in 2 10 2 the diamagnetic anisotropies, both the molar and molecular principal susceptibilities. References to anisotropic data are already given in 2 10 1; thus this table gives a quick survey of all magnitudes available for each substance in this volume. The symbols and units are the same as in Volume II/ 9."

Oxidation numbers and oxidation states / Christian K. Jorgensen

Public ISBD Titre : Oxidation numbers and oxidation states Type de document : texte imprimé Auteurs : Christian K. Jorgensen Editeur : Berlin, Heidelberg : Springer Verlag Année de publication : 1969 Importance : 291 p. ISBN/ISSN/EAN : 978-3-642-87760-5 Langues : Anglais (eng) Catégories : Généralités en Chimie Tags : THEORETICAL CHEMISTRY  VALENCE Index. décimale : B-A Résumé : "The correlation of spectroscopic and chemical investigations in recent years has been highly beneficial of many reasons. Around 1950, no valid explanation was available of the colours of compounds of the five tran­sition groups. Later, it was possible to identify the excited levels with those expected for an electron configuration with a definite number of electrons in the partly filled shell. It is not generally recognized that this is equivalent to determining spectroscopic oxidation states related to the preponderant electron configuration and not to estimates of the fractional atomic charges. This brings in an entirely different type of description than the formal oxidation numbers used for characterizing compounds and reaction schemes. However, it must be realized that collectively oxidized ligands, formation of cluster-complexes and catenation may prevent the oxidation state from being well-defined."
