This Solutions Manual accompanies the second edition of Donald McQuarrie’s Quantum Chemistry. It contains each of the more than 700 problems in the text, followed by a detailed solution. This Solutions Manual to accompany Raymond Chang’s Physical Chemistry for the Chemical and Biological Sciences restates each of the 1020 innovative chapter-ending problems in the text, followed by a detailed solution. Each solution is approached with the same conversational style that the authors use in their own classrooms as they try to “teach” solutions to the problems rather than simply giving out answers. One hundred forty-three figures and diagrams are used to illustrate the solutions. Both authors are recent recipients of the Henry Dreyfus Teacher-Scholar award and bring to the manual effective pedagogy as well as the vitality of modern physical chemistry.
