This timely and unique publication is designed for graduate students and researchers in inorganic and materials chemistry and covers bonding models and applications of symmetry concepts to chemical systems. The book discusses the quantum mechanical basis for molecular orbital concepts, the connections between molecular orbitals and localized views of bonding, group theory, bonding models for a variety of compounds, and the extension of these ideas to solid state materials in band theory. Unlike other books, the concepts are made tangible to the readers by guiding them through their implementation in MATLAB functions. No background in MATLAB or computer programming is needed; the book will provide the necessary skills. Key Features Visualization of the Postulates of Quantum Mechanics to build conceptual understanding MATLAB functions for rendering molecular geometries and orbitals Do-it-yourself approach to building a molecular orbital and band theory program Introduction to Group Theory harnessing the 3D graphing capabilities of MATLAB Online access to a growing collection of applications of the core material and other appendices Bonding through Code is ideal for first-year graduate students and advanced undergraduates in chemistry, materials science, and physics. Researchers wishing to gain new tools for theoretical analysis or deepen their understanding of bonding phenomena can also benefit from this text. About the Author Daniel Fredrickson is a Professor in the Department of Chemistry at the University of Wisconsin–Madison, where his research group focuses on understanding and harnessing the structural chemistry of intermetallic phases using a combination of theory and experiment. His interests in crystals, structure, and bonding can be traced to his undergraduate research at the University of Washington (B.S. in Biochemistry, 2000) with Prof. Bart Kahr, his Ph.D. studies at Cornell University (2000–2005) with Profs. Stephen Lee and Roald Hoffmann, and his post-doctoral work with Prof. Sven Lidin at Stockholm University (2005–2008). As part of his teaching at UW–Madison since 2009, he has worked to enhance his department’s graduate course, Physical Inorganic Chemistry I: Symmetry and Bonding, through the incorporation of new material and the development of computer-based exercises.

This book examines the linguistic and interactional mechanisms through which people bond or feel bonded with one another by analyzing situated discourse in Japanese contexts. The term “bonding” points to the sense of co-presence, belonging, and alignment with others as well as with the space of interaction. We analyze bonding as established, not only through the usage of language as a foregrounded code, but also through multi-layered contexts shared on the interactional, corporeal, and socio-cultural levels. The volume comprises twelve chapters examining the processes of bonding (and un-bonding) using situated discourse taken from rich ethnographic data including police suspect interrogations, Skype-mediated family conversations, theatrical rehearsals, storytelling, business email correspondence and advertisements. While the book focuses on processes of bonding in Japanese discourse, the concept of bonding can be applied universally in analyzing the co-creation of semiotic, pragmatic, and communal space in situated discourse.

This book explores chemical bonds, their intrinsic energies, and the corresponding dissociation energies which are relevant in reactivity problems. It offers the first book on conceptual quantum chemistry, a key area for understanding chemical principles and predicting chemical properties. It presents NBO mathematical algorithms embedded in a well-tested and widely used computer program (currently, NBO 5.9). While encouraging a "look under the hood" (Appendix A), this book mainly enables students to gain proficiency in using the NBO program to re-express complex wavefunctions in terms of intuitive chemical concepts and orbital imagery.

The Relationship Code is the report of a longitudinal study, conducted over a ten-year period, of the influence of family relationships and genetic factors on competence and psychopathology in adolescent development. The sample for this landmark study included 720 pairs of same-sex adolescent siblings--including twins, half siblings, and genetically unrelated siblings--and their parents. Using a clear expressive style, David Reiss and his coinvestigators identify specific mechanisms that link genetic factors and the social environment in psychological development. They propose a striking hypothesis: family relationships are crucial to the expression of genetic influences on a broad array of complex behaviors in adolescents. Moreover, this role of family relationships may be very specific: some genetic factors are linked to mother-child relationships, others to father-child relations, some to relationship warmth, while others are linked to relationship conflict or control. The specificity of these links suggests that family relationships may constitute a code for translating genetic influences into the ontogeny of behaviors, a code every bit as important for behavior as DNA-RNA.

This groundbreaking work, the culmination of more than 10 years of research, presents a breakthrough theory of chemical bonding across the periodic table. Professor Epiotis, an internationally known and respected member of the theoretical community, challenges the conventional chemical concepts that underlie popular theories of chemical bonding. Building on his insight that electron-electron repulsion is the single crucial variable that differentiates one chemical system from another, the author formulates, explains, and applies a new approach based on nonorthogonal valence bond methodology that amounts to nothing less than a revolutionary unified theory of chemical boding across the periodic table. This work represents the first post-Pauling theory of chemical bonding. New theory means new formulae, and this work is about new chemical formulae that lead to the self-consistent rationalization of existing facts and, even more important, the design of new chemistry.

As chemical bonds are not observable, there are various theories and models for their description. This book presents a selection of conceptually very different and historically competing views on chemical bonding analysis from quantum chemistry and quantum crystallography. It not only explains the principles and theories behind the methods, but also provides practical examples of how to derive bonding descriptors with modern software and of how to interpret them.
