Rare Linus PAULING 1st edit/1st print Introduction to Quantum Mechanics With Applications to Chemistry [Hardcover] PAULING, Linus and E. Bright Wilson [Hardcover] PAULING, Linus and E. Bright Wilson
This is a wonderful book for not only chemists but for anyone really interested in quantum mechanics. It is amazingly clear considering what it is trying to explain. One thing should be noted and that is that it claims that "extensive knowledge of mathematics is not required" but the maths can be heavy at times. If you don't understand partial derivative equations then you may not get the full enjoyment of what the book is saying(as this is the most advanced mathematics that you need). But at the same time there is enough text that you would certainly be able to read the book and take a huge amount from it.
