Designed for a two-semester introductory course sequence in physical chemistry, this text presents core principles and topics. Straightforward and streamlined, it presents the necessary amount of detail for comprehension. Organized in such a way that the various topics covered are connected to each other, it allows students to see physical chemistry as an interconnected discipline and not a series of unrelated concepts. Each chapter in this new edition has been thoroughly updated and includes new information on computational applications, more end of chapter problems, and new chapters on nanotechnology and surface chemistry.
