Summary: Excelent Reference for Cheap
Review: After all these years Pauling & Wilson still is one of the fundamental works on making chemistry an "exact" science. This Dover edition made it affordable to any undergrad/grad student, no more excuses for using such junk approaches like the first chapters on the subject like Phys Chem/Atkins

Summary: Philosophy: By Socrates, Quantum Chemistry: By Linus Pauling
Review: How would an "Introduction to Philosophy" by Socrates or a "Basics of the Piano" by Mozart sound like? This is something similar. Linus Pauling, the unprecedented pioneer of the application of Quantum Mechanics to Chemistry, had written this book in the 1930s as perhaps the first introduction to QM for Chemists, supported by his colleague, E Bright Wilson, a brilliant chemist in his own right. A generation of Chemists grew up learning from this book, and its content is as relevant and articulate today as it was then. Hundreds of Quantum Chemistry books, some of which are excellent, have been written in the times since it was first published. But this book still retains an incomparable flavour that brings out the fundamental nature of QM and Chemical Bonding. I have to admit that I found this book slightly difficult, because Pauling and Wilson, although being extremely lucid, never compromise on the Math. But gradually I learnt that this is the kind of book which belongs in the same category of, say, Ernest Eliel's stereochemistry book. That means that every moment you spent on it will be worth it, even if it takes you a very long time to go through it. This is one of those books where every word is carefully thought and then stated, making the journey difficult at places, but always rewarding. And why not. It is hard to imagine anyone else writing with so much confidence on the topic. So it is important not to gloss over this book quickly and then discard it as being dry, but persist in reading it and get insight out of it. The book opens with a discussion of Lagrangian mechanics and discusses some simple examples of its applications. It then moves on to the basic principles of QM, and comes to the Hydrogen molecule, which was the pinnacle of succcess for the Physicists. I think that this book has the best discussion of the H molecule ever written. I have seen other excellent Quantum Chemistry books giving a reference to this work whenever they discuss the H molecule. Moreover, I believe that a thorough understanding of the H molecule is of paramount importance for understanding any further application of QM to Chemistry. Discussion of this molecule opens the door to understanding orbitals, spherical harmonics, angular momentum and all the important concepts in theoretical Chemistry. So the book will score top points for this alone. Later on there are excellent discussions of the Variational Method, Perturbation theory and finally the various important approximations like Hartree-Fock theory and the structure of molecules. The appendices deal with detailed discussions of derivation and some mathematical topics. All in all, a clear and extremely lucid presentation, well worth every moment you can spend on it, by one of the greatest scientists of all time.

Summary: Simple with everything
Review: If you are an undergraduate and you want everything you need, this is the book. The lack of matrix mechanics makes this book unsuitable for serious graduate students, though. I think it would actually be best for 1st or 2nd year serious undergraduate chemists who are well acquainted with differential equations.

Summary: Richly historical account of molecular quantum mechanics
Review: In many ways, this is still my favourite quantum mechanics text. Why? Because the text is completely grounded in the quantum mechanics of atoms and molecules. Historically, Linus Pauling spent his post-doc working throughout Europe where he absorbed the, then, new theory of quantum mechanics. However, the physicists that he learnt q.m. from only analysed the physics of, relatively simple, atomic systems. It would require someone with an immense breadth of knowledge in chemistry to make quantum mechanics come alive for molecules. This was Linus Pauling. Pauling first applied q.m. to such diverse topics as: the chemical bond, resonance energy, electronegativity, crystal structure of molecules and hydrogen bonds. And it shows. The uniqueness of this q.m. textbook is that it gives immensely detailed references to the different ways the early physicists/chemists attacked the q.m. of bonds in molecules. Many different ansatz's and approximations to pertubation problems are given. And Pauling should know, for he was right in the thick of it. The historical value of these references alone is worth the price of this book. It's a real shame that most modern books leave these out, because a discussion of these approximations methods give a lot of insight to q.m. in molecules. In contrast, I find modern textbooks on physical chemistry to be often lacking in deep physical insight. However, textbooks written by physicists run into all sorts of esoteric directions like quantum entanglement and the uncertainty principle and as a previous reviewer noted, Pauling's books says nothing about scattering and hardly anything on spin. This is probably because chemists aren't interested in what happens to particles in beams or Stern-Gerlach experiments. They are more interested in ionisation energy, enthalpies and bond energies. Nevertheless, for out-and-out modern-day quantum physicists, Pauling's explanation of aspects of quantum mechanics will seem quaint, overly pictorial and concrete, e.g. discussion of *actual* orbits. And it is. However, for chemists and even atomic physicists, pondering such esoteric questions clouds the immense power of quantum mechanics in explaining the detailed properties of atoms and molecules.

Summary: Quantum Chemistry at its best
Review: Linus Pauling revolutionised the chemical world by his magnum opus 'The Nature of the Chemical Bond' which would come out a few years after this book. This work first came out in the 30s when people were beginning to perceive the potential uses of quantum mechanics in Chemistry, it reveals everything you need to know about the foundations of quantum chemistry and it's indeed a priceless gem for any aspiring chemist. The problem with newer books is that they present the subject in a very dogmatic and, at times, superficial way leaving the student often puzzled and confused with all the mathematical formalities. This book has everything and I mean EVERYTHING ! At the risk of becoming pedantic for those more knowledgeable in calculus and linear algebra, every calculation and every reasoning is justified. The formalities are all unveiled and minimized but it still digs deep into the characterization of the theories of the chemical bond, electronic structure, the infamous group theory and some basic spectroscopy.

Summary: Hone your technical skills with Pauling.
Review: Linus Pauling's treatise on quantum chemistry is even more brilliant than that on general chemistry. His vivid and clear explanation makes quantum theory so interesting and appealing to learn. Instead of going through the obscure mathematics and operator mechanics, Pauling conveys the essence of quantum mechanics in very simple language. Maybe this is how Pauling distinguishes himself as a Nobel Prize laureate. I studied Donald McQuarrie "Physical Chemistry: A Molecular Approach" (you may find my review for McQuarrie here as well) and found McQuarrie so much more understandable than Atkins. Yet Pauling's account on the subject is even more concise and motivating. The book teaches basic concepts but also ensures understanding of applied theory. While "Introduction to Quantum Mechanics" might not be as reader-friendly as its counterpart in general chemistry, I highly recommend this book for all chemistry students and those who want to adventure in advanced chemistry.

Summary: Oldie but goodie
Review: This is a great, simple presentation of the Schroedinger viewpoint. There is no Dirac representation and no matrix mechanics. However, there is much to be liked about this book and it is a pleasure to read. Those who are baffled completely by quantum mechanics will find this an enlightening introduction and a simple understandable place to start. This is another one of those lesser known gems.
