You cannot expect to succeed in a serious chemistry course without solving problems, which are universally used to illustrate concepts and to test understanding. This manual offers detailed solutions to all of the odd-numbered problems in the text to assist you in working through them.

David W. Oxtoby became the ninth president of Pomona College on July 1, 2003. An internationally noted chemist, he previously served as dean of physical sciences at the University of Chicago. At Pomona, he holds a coterminous appointment as president and professor of chemistry. Before coming to Pomona, he was associated with the University of Chicago for nearly three decades, with brief interludes to serve as a visiting professor at such places as the University of Paris; the University of Bristol in Great Britain; and the University of Sydney in Australia.

As a research chemist, he is author or co-author of more than 165 scientific articles on such subjects as light scattering, chemical reaction dynamics and phase transitions. He has been invited as a guest lecturer at conferences and institutions around the globe. In addition to co-authoring Principles of Modern Chemistry and Chemistry: Science of Change, he has received fellowships from the Guggenheim, von Humboldt, Dreyfus, Sloan, Danforth and National Science foundations.

Oxtoby is a fellow of the American Physical Society and a member of the American Chemical Society and the American Association for the Advancement of Science.

After earning his bachelor's degree, summa cum laude, from Harvard University, he went on to earn his Ph.D. on the opposite coast, at the University of California, Berkeley.

Oxtoby and his wife, Claire, are the parents of three children, Mary Christina, John and Laura.H.P. Gillis conducts experimental research in the physical chemistry of electronic materials, emphasizing phenomena at solid surfaces and interfaces. Dr. Gillis received his B.S. (Chemistry and Physics) at Louisiana State University and his Ph.D. (Chemical Physics) at The University of Chicago. After postdoctoral research at the University of California-Los Angels and 10 years with the technical staff at Hughes Research Laboratories in Malibu, California, Dr. Gillis joined the faculty of Georgia Institute of Technology. Dr. Gillis moved to University of California-Los Angeles, where he currently serves as Adjunct Professor of Materials Science and Engineering. He has taught courses in general chemistry, physical chemistry, quantum mechanics, surface science, and materials science at Georgia Institute of Technology and at UCLA.Alan Campion is Dow Chemical Company Professor of Chemistry and University Distinguished Teaching Professor at The University of Texas at Austin. A member of the faculty for more than 25 years (and former Department Chairman), Professor Campion's research in surface physics and chemistry and condensed matter spectroscopy has been presented in more than 120 scientific publications and more than 100 invited lectures worldwide. He has been an Alfred P. Sloan Fellow, a Camille and Henry Dreyfus Teacher Scholar and a Guggenheim Fellow and he was awarded the Coblentz Memorial Prize in Molecular Spectroscopy. Professor Campion developed the curriculum for the junior/senior level Physical Chemistry course, the Chemistry in Context course for non-science and engineering students, and the chemistry and biochemistry majors general chemistry course, which also serves as an honors course for the College of Natural Sciences. He has been recognized for his teaching by both students and peers with numerous, campus-wide teaching awards, including the prestigious Jean Holloway Award for Teaching Excellence in the Colleges of Liberal Arts and Natural Sciences (student-selected) and his induction into the Academy of Distinguished Teachers (peer-nominated).
