Valence theory / John N. Murrell

Public ISBD Titre : Valence theory Type de document : texte imprimé Auteurs : John N. Murrell ; S.F.A. Kettle ; J.M. Tedder Editeur : New York : John Wiley & Sons Année de publication : 1965 Importance : 401 p. Langues : Anglais (eng) Catégories : Chimie théorique Tags : CHEMISTRY-Physical and Theoretical  VALENCE Index. décimale : B-H Résumé : "The book has been based on lectures given for the past four years at the University of Sheffield. Our experience has been that the student only obtains a full grasp of the subject when he has successfully tackled some problems, and we consider that the problems in this book are an essential part of the text; some of the problems provide proofs of statements made in the text. A student benefits most if he is given the minimum of help necessary to enable him to solve the problem. To take a step in this direction we have provided hints to the problems at the end of the book. The student should first try the problems without the hints, but with their help most students should be able to obtain the solutions. The first five chapters are intended for first year students, since we feel that an early grasp of such concepts as the orbital and the electron-pair bond are necessary for any course in experimental chemistry. The more formal mathematical aspects of the book start in chapter 6 when it has been assumed that the student has received some mathematical training during his first year. These later chapters also assume a knowledge of other branches of chemistry." Authors' preface Cote : B-H042 (SdS) Num_Inv : 419 Valence theory [texte imprimé] / John N. Murrell ; S.F.A.

Multivalency: concepts, research and applications / Huskens, Jurriaan

Public ISBD Titre : Multivalency: concepts, research and applications Type de document : texte imprimé Auteurs : Huskens, Jurriaan, Éditeur scientifique ; Prins, Leonard J., Éditeur scientifique ; Haag, Rainer, Éditeur scientifique ; Ravoo, Bart Jan, Éditeur scientifique Editeur : Oxford : Wiley Année de publication : 2018 Importance : xiii, 393 p. ISBN/ISSN/EAN : 978-1-119-14346-8 Langues : Anglais (eng) Catégories : Chimie : Généralités Tags : VALENCE  VALENCE-THEORETICAL CHEMISTRY  BIOCHEMISTRY Index. décimale : B-A Résumé : Multivalency is a widespread phenomenon, with applications spanning supramolecular chemistry, materials chemistry, pharmaceutical chemistry and biochemistry. This advanced textbook provides students and junior scientists with an excellent introduction to the fundamentals of multivalent interactions, whilst expanding the knowledge of experienced researchers in the field. Multivalency: Concepts, Research & Applications is divided into three parts. Part one provides background knowledge on various aspects of multivalency and cooperativity and presents practical methods for their study. Fundamental aspects such as thermodynamics, kinetics and the principle of effective molarity are described, and characterisation methods, experimental methodologies and data treatment methods are also discussed. Parts two and three provide an overview of current systems in which multivalency plays an important role in chemistry and biology, with a focus on the design rules, underlying chemistry and the fundamental principles of multivalency. The systems covered range from chemical/materials-based ones such as dendrimers and sensors, to biological systems including cell recognition and protein binding. Examples and case studies from biochemistry/bioorganic chemistry as well as synthetic systems feature throughout the book. Introduces students and young scientists to the field of multivalent interactions and assists experienced researchers utilising the methodologies in their work Features examples and case studies from biochemistry/bioorganic chemistry, as well as synthetic systems throughout the book Edited by leading experts in the field with contributions from established scientists Multivalency: Concepts, Research & Applications is recommended for graduate students and junior scientists in supramolecular chemistry and related fields, looking for an introduction to multivalent interactions. It is also highly useful to experienced academics and scientists in industry working on research relating to multivalent and cooperative systems in supramolecular chemistry, organic chemistry, pharmaceutical chemistry, chemical biology, biochemistry, materials science and nanotechnology.

Oxidation numbers and oxidation states / C.K. Jorgensen

ISBN/ISSN/EAN : 978-3-642-87760-5 Langues : Anglais (eng) Catégories : Chimie : Généralités 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."
