I've been trying to learn more about physical chemistry, especially since only after graduating did I realize how neat of a field it is. In my undergraduate program, we had a course in classical thermodynamics (we never reached statistical mechanics or kinetics), then there was a quantum chemistry course (which, while challenging and interesting, was still kind of narrow in its scope). Also, I had two semesters of non-calculus intensive physics (calculus was used, but as a whole, the course was a watered-down version) and two semesters of calculus (all that my degree required). The physical chemistry textbooks I used in school were: -Thermodynamics, Statistical Thermodynamics, and Kinetics, Engel & Reid -Introduction to Quantum Mechanics in Chemistry, Materials Science, and Biology, S.M. Blinder -Experiments in Physical Chemistry, Garland, Nibler, & Shoemaker I was most impressed with Garland et. al. Unfortunately, it is not a general textbook and I used it only in my physical chemistry lab. S.M. Blinder was good and accessible and I learned a lot from it, but it seemed to compromise on depth. The semester that I took Quantum Chem, the department had just switched to Blinder from Donald McQuarrie's book. I was not impressed with Engel & Reid, and would like another book to replace it in my library. Anyhow, there are tons of books on Amazon.com about thermodynamics, statistical thermodynamics, and quantum mechanics. For classical thermo, I'm looking for something more as a reference. For statistical thermodynamics, I need an introductory book. For Quantum Mechanics, I'd prefer an introductory book that has more of a chemistry focus than a physics focus (I'm leaning toward McQuarrie, but want to hear some recommendations first). [EDIT] I realized that I should give more background as to myself. Currently, I'm working for a professor at a different university who does theoretical chemistry. Also, I'm taking more math courses (Multivariable Calc. and Linear Algebra at least), so hopefully that won't hold me back in the future. I'd *really* like a book that has a good explanation of group theory applications to QM. Right now, I have Group Theory and Chemistry by David Bishop, which is excellent.
