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

This revised and up-dated second edition provides a current insight into how the fundamental principles of the chemistry of colour are applied in dyes and pigments. The text has been expanded and re-written throughout, while largely maintaining the structure of the first edition. In particular, the chapter on functional dyes has been substantially re-written to embrace the significant developments in chemistry and technology that this area has experienced in the last decade. As industry and society have become increasingly sensitive towards environmental issues, the chapter describing how the colour industry has been responding is expanded to reflect this growing importance. A new chapter is introduced on colour in cosmetics, with particular emphasis on hair dyes, reflecting the growing international, industrial significance of this topic. This chapter is co-written with Dr Olivier Morel. Colour Chemistry will be of interest to academics and industrialists who are specialists in colour science or who have involvement with the diverse range of coloured materials, for example traditional application in textiles, paints, printing inks, plastics and cosmetics, and functional applications in electronics and biology. Broad and balanced in its coverage, this book provides an introduction to the chemistry of colour that is ideal for students, graduates and those in industry and academia seeking an introduction to the topic. Robert Christie is a Professor in Colour Chemistry and Technology at Heriot-Watt University, Scotland, and a Distinguished Adjunct Professor at the King Abdulaziz University, Saudi Arabia.

There is a logical progression from atomic structure to molecular structure to properties of substances based on molecular structures, to behavior of solids, etc.The textbook contains a balance of topics in theoretical and descriptive chemistry. For example, the hard-soft interaction principle is used to explain hydrogen bond strengths, strengths of acids and bases, stability of coordination compounds, etc. Discussion of elements begins with survey chapters focused on the main groups, while later chapters cover the elements in greater detail. Each chapter opens with narrative introductions and includes figures, tables, and end-of-chapter problem sets. This new edition features updates throughout, with an emphasis on bioinorganic chemistry and a new chapter on nanostructures and graphene. More in-text worked-out examples encourage active learning and prepare students for their exams.This text is ideal for advanced undergraduate and graduate-level students enrolled in the Inorganic Chemistry course.

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.
