Modern Quantum Chemistry: Introduction to Advanced Electronic Structure Theory (Dover Books on Chemistry)
In modern quantum chemistry, the electronic structure of a molecule is studied using advanced theories that take into account the behavior of electrons in the presence of both Coulombic and magnetic forces. These theories allow for a more accurate description of the electronic structure of molecules than the more traditional approaches that focus on the Born-Oppenheimer approximation.
One of the most important features of modern quantum chemistry is the use of group theory to predict the behavior of electrons in molecules. Group theory allows for the determination of the symmetry of a molecule and the energy levels of its electrons. In addition, group theory can be used to predict the shapes of molecules and the types of bonding that can occur between them.
Another important feature of modern quantum chemistry is the use of quantum mechanical techniques to solve problems that are intractable with classical methods. Quantum mechanical techniques allow for the solution of problems that involve large numbers of particles or that are otherwise too complex for classical methods.
One of the most important applications of modern quantum chemistry is in the study of organic reactions. By understanding the electronic structure of molecules, chemists can predict the products of reactions and design new reactions that will produce desired products.
