Ira N. Levine

If you are taking graduate quantum chemistry and Quantum chemistry by Levine is what you are suing, this is a must-have. It is fairly inexpensive and provides the solutions for all the problems in the book. It is an excellent solution manual if you are trying to do the exercises to increase your understanding of the material in the book.

This is the book we used in my graduate Quantum chemistry course. It is an excellent book for a graduate course. A fundamental knoweldge of calculus, Quantum mechanics, and chemistry is a good idea before jumping into this book. Also, the solution manual for this book is extremely useful.

A pretty good, but now-dated text.

This is Chemistry analogue of James Joyce's Ulysses. Sometimes less is more, I'd recommend other texts.
