By Robert G. Parr

This booklet is a rigorous, unified account of the elemental rules of the density-functional concept of the digital constitution of topic and its functions to atoms and molecules. Containing an in depth dialogue of the chemical strength and its derivatives, it presents an realizing of the ideas of electronegativity, hardness and softness, and chemical reactivity. either the Hohenberg-Kohn-Sham and the Levy-Lieb derivations of the fundamental theorems are provided, and vast references to the literature are integrated. introductory chapters and a number of other appendices offer all of the heritage fabric invaluable past an information of basic quantum conception
