"Ab initio" quantum chemistry has emerged as an important tool in chemical research and is applied to a wide variety of problems in chemistry and molecular physics. Recent developments of computational methods have enabled previously intractable chemical problems to be solved using rigorous quantum-mechanical methods.This is the first comprehensive up-to-date and technical work to cover all the important aspects of modern molecular electronic-structure theory. Topics covered in the book include: Second quantization with spin adaptationGaussian basis sets and molecular-integral evaluationHartree-Fock theoryConfiguration-interaction and multi-configurational self-consistent theoryCoupled-cluster theory for ground and excited statesPerturbation theory for single- and multi-configuration statesLinear-scaling techniques and the fast multiple methodExplicitly correlated wave functionsBasis-set convergence and extrapolationCalibration and benchmarking of computational methods, with applications to molecular equilibrium structures, atomization energies and reaction enthalpies."Molecular Electronic-Structure" Theory makes extensive use of numerical examples, designed to illustrate the strengths and weaknesses of each method treated. In addition, statements about the usefulness and deficiencies of the various methods are supported by actual examples, not just model calculations. Problems and exercises are provided at the end of each chapter, complete with hints and solutions.This book is a must for researchers in the field of quantum chemistry as well as for nonspecialists who wish to acquire a thorough understanding of "ab initio" molecular electronic-structure theory and its applications to problems in chemistry and physics. It is also highly recommended for the teaching of graduates and advanced undergraduates.
