DEEP, THEORETICAL RESOURCE ON THE ESSENCE OF CHEMISTRY, EXPLAINING A VARIETY OF IMPORTANT CONCEPTS INCLUDING REDOX STATES AND BOND TYPES _Exploring Chemical Concepts Through Theory and Computation _provides a comprehensive account of how the three widely used theoretical frameworks of valence bond theory, molecular orbital theory, and density functional theory, along with a variety of important chemical concepts, can between them describe and efficiently and reliably predict key chemical parameters and phenomena. By comparing the three main theoretical frameworks, readers will become competent in choosing the right modeling approach for their task. The authors go beyond a simple comparison of existing algorithms to show how data-driven theories can explain why chemical compounds behave the way they do, thus promoting a deeper understanding of the essence of chemistry. The text is contributed to by top theoretical and computational chemists who have turned computational chemistry into today’s data-driven and application-oriented science. _Exploring Chemical Concepts Through Theory and Computation _discusses topics including: * Orbital-based approaches, density-based approaches, chemical bonding, partial charges, atoms in molecules, oxidation states, aromaticity and antiaromaticity, and acidity and basicity * Electronegativity, hardness, softness, HSAB, sigma-hole interactions, charge transport and energy transfer, and homogeneous and heterogeneous catalysis * Electrophilicity, nucleophilicity, cooperativity, frustration, homochirality, and energy decomposition * Chemical concepts in solids, excited states, spectroscopy and machine learning, and catalysis and machine learning, as well as key connections between related concepts Aimed at both novice and experienced computational, theoretical, and physical chemists, _Exploring Chemical Concepts Through Theory and Computation _is an essential reference to gain a deeper, more advanced holistic understanding of the field of chemistry as a whole.
