Book Description
Electronic Energy Levels of Transition Metal Complexes guides the reader to understand how to comprehensively calculate (predict, reconstruct) electronic energy levels of separation between 0,1 to 30,000 cm-1 in d1 to d9 transition metal complexes. The applied apparatus helps to understand the individual effect of the interelectron repulsion, crystal field strength, spin-orbit coupling and the magnetic field for any symmetry. Symmetry labels can be attached to energy levels (eigenvalues) by analyzing the eigenvectors of the model Hamiltonian either at the level of crystal-field terms or crystal-field multiplets.This book includes basic formulae for matrix elements of the model Hamiltonian and a huge number of results presented as graphs identifying the order of the energy levels and their labelling using the group (double group) irreducible representations. Utilization of the generated energy levels in electron spectroscopy, electron spin resonance and magnetochemistry is presented. Massive modelling was done using the desktop computers. - Covers advanced methodology for general cases, electronic terms and spin-orbit multiplets in the crystal field of any symmetry, and extensive modelling - Analyzes extensive modeling of energy levels and magnetic functions fo complexes of lower symmetry - Presents energy level diagrams and magnetic functions are presented for the most important cases, such as the octahedron, elongated tetragonal pyramid, compressed tetragonal pyramid, tetrahedron, prolate bisphenoid, flattened bisphenoid, trigonal bipyramid, tetragonal bipyramid, and o-rhombic bypyramid for d1 to d9 systems

Publisher: Springer Science & Business Media
ISBN: 9783540629221
Category : Science
Languages : en
Pages : 276
Book Description
The unique properties and applications of transition metal compounds have long fascinated both physicists and chemists. This volume presents theoretical and experimental studies for a deeper understanding of the electronic and vibronic properties of these compounds. In particular, an introduction into properties of spin sublevels of dd*, dÂ*, and ÂÂ* states is given, and a modern ligand field theory based on the Angular Overlap Model is presented. In experimental case studies it is shown how to characterize different types of electronic transitions using modern methods of laser spectroscopy. Consequences of spin-orbit coupling, zero-field splittings, spin-lattice relaxations, chromophore-matrix interactions, Herzberg-Teller/Franck-Condon activities, and localization/delocalization properties are treated.

Molecular Orbitals of Transition Metal Complexes
Author: Yves Jean
Publisher: Oxford University Press
ISBN: 0198530935
Category : Science
Languages : en
Pages : 288
Book Description
This book starts with the most elementary ideas of molecular orbital theory and leads the reader progressively to an understanding of the electronic structure, geometry and, in some cases, reactivity of transition metal complexes. The qualitative orbital approach, based on simple notions such as symmetry, overlap and electronegativity, is the focus of the presentation and a substantial part of the book is associated with the mechanics of the assembly of molecular orbital diagrams. The first chapter recalls the basis for electron counting in transition metal complexes. The main ligand fields (octahedral, square planar, tetrahedral, etc.) are studied in the second chapter and the structure of the "d block" is used to trace the relationships between the electronic structure and the geometry of the complexes. The third chapter studies the change in analysis when the ligands have pi-type interactions with the metal. All these ideas are then used in the fourth chapter to study a series of selected applications of varying complexity (e.g. structure and reactivity). The fifth chapter deals with the "isolobal analogy" which points out the resemblance between the molecular orbitals of inorganic and organic species and provides a bridge between these two subfields of chemistry. The last chapter is devoted to a presentation of basic Group Theory with applications to some of the complexes studied in the earlier chapters.

The Quantum in Chemistry
Author: Roger Grinter
Publisher: John Wiley & Sons
ISBN: 0470017627
Category : Science
Languages : en
Pages : 474
Book Description
This book explores the way in which quantum theory has become central to our understanding of the behaviour of atoms and molecules. It looks at the way in which this underlies so many of the experimental measurements we make, how we interpret those experiments and the language which we use to describe our results. It attempts to provide an account of the quantum theory and some of its applications to chemistry. This book is for researchers working on experimental aspects of chemistry and the allied sciences at all levels, from advanced undergraduates to experienced research project leaders, wishing to improve, by self-study or in small research-orientated groups, their understanding of the ways in which quantum mechanics can be applied to their problems. The book also aims to provide useful background material for teachers of quantum mechanics courses and their students.

Book Description
PRINCIPLES OF MODERN CHEMISTRY has dominated the honors and high mainstream general chemistry courses and is considered the standard for the course. The fifth edition is a substantial revision that maintains the rigor of previous editions but reflects the exciting modern developments taking place in chemistry today. Authors David W. Oxtoby and H. P. Gillis provide a unique approach to learning chemical principles that emphasizes the total scientific process'from observation to application'placing general chemistry into a complete perspective for serious-minded science and engineering students. Chemical principles are illustrated by the use of modern materials, comparable to equipment found in the scientific industry. Students are therefore exposed to chemistry and its applications beyond the classroom. This text is perfect for those instructors who are looking for a more advanced general chemistry textbook.
