with Applications to Chemistry Linus Pauling, E. Bright Wilson New York, London, McGraw-Hill book company, 1935. Description: A classic and excellent introduction to quantum mechanics. Importance: One of the earliest books that introduced quantum mechanics to chemists. It remains well loved by many to this day. Valence C. A Coulson Oxford, Clarendon Press, 1952. The latest edition is called Coulson's Valence, 3rd Edition, Roy McWeeny, Oxford University Press, 1980 Description: A classic introduction to valence and the theory of chemical binding. Importance: This book is credited with causing the expansion of interest in molecular orbital theory from the 1950s. The Nature of the Chemical Bond and the Structure of Molecules and Crystals; An Introduction to Modern Structural Chemistry Linus Pauling Ithaca, N.Y., London, Cornell University Press; H. Milford, Oxford University Press, 1940. Description: A classic that was the first general book to introduce quantum mechanics to chemists. Importance: Probably more than any other book, introduced quantum mechanics and, in particular, valence bond theory to experimental chemists. Density-Functional Theory of Atoms and Molecules R. G. Parr and W. Yang, Oxford University Press, New York, 1989. Description: A very thorough and scholarly account of density functional theory. Importance: This is a good introduction to the subject, but has particular significance in the way it describes how the theory throws new light on old chemical concepts such as electronegativity. Car–Parrinello molecular dynamics Roberto Car and Michele Parrinello, Phys. Rev. Lett. 55, 2471 (1985) Description: Unified Approach for Molecular Dynamics and Density Functional Theory. Importance: First demonstration of ab-initio molecular dynamics, where the forces are computed on-the-fly by means of quantum mechanical electronic structure calculations. Supramolecular chemistry Supramolecular Chemistry – Concepts and Perspectives Jean-Marie Lehn , VCH, Description: Comprehensive textbook written by topic creator. Importance: Most-popular textbook on subject (according to Amazon.com). Lehn coined the term "supermolecule" in '73, developed the concept of supramolecular chemistry in '78, and won the Nobel Prize for his supramolecular chemistry work in ’87.
