This book introduces relativistic methods in quantum chemistry to non-experts and students. Its five sections cover classically relativity background; the Dirac question; four component methods, including symmetry, correlation, and properties; approximate methods, including perturbation theory, transformed Hamiltonians, regular approximations, matrix approximations, and pseudopotential methods; and an overview of relativistic effects on bonding.

"This book is an excellent guide to the theoretical background and the computational application of relativistic quantum chemistry. It lives up to the claim of being readable by the non-relativistic quantum chemist, and I can recommend it to anyone interested in using or developing these methods." - Chemistry World
