Fostering an intuitive understanding of chemistry, ** ***Physical Chemistry: Quantum Chemistry and Molecular Interactions* presents the structure and unity of the theoretical framework of modern chemistry in a progression from the single atom to the bulk limit. Employing an engaging and somewhat informal tone, this new text delivers a superior presentation of rigorous mathematical derivations, thermodynamics, and quantum theory and mechanics in a manner that is accessible and applicable to diverse readers.
