Introduction to Quantum Mechanics with Application

I was more than satisfied with my order, it was the blue book I wanted, it was on great condition, much better than expected, and was for a great price. Great buy, truly thankful.

Masterpiece!!!!!!

A masterpiece written by a great by one of the greatest genius of chemistry. Written in a clear and comprehensible way, the book is a fundamental work to understand quantum mechanics applied to chemistry.

著者のポーリングは化学に量子論を次々と適用させて、近代量子化学の礎をつくりあげた大化学者である。 この本は化学書と言うよりは、本格的な量子力学の教科書と言う方がふさわしいが、実に良くできている。 普通の量子化学の本と違うのは、まずきちんと解析力学の議論から量子論へと展開している点である。 化学の学生はあまり解析力学を本格的に勉強する機会が少なく、量子論と古典力学の対応が今ひとつピンとこないまま分子軌道法などを使う事になる。 しかしこの本できちんと学べば、本格的な量子化学シミュレーションに踏み込んでも、そう問題はないだろう。 世界的にも非常に有名で、値段も驚くほど安いが、得られる知識と考察は非常に深い。

This is an introductory quantum mechanics book that focuses exclusively on how this new (at the time this book was written) mechanics clarifies the nature of chemical bonds. By focusing on this problem this book is able to provide a simplified treatment of quantum mechanics as unbound electron states can be excluded. The treatment is further simplified by ingoring all magnetic effects such as spin-orbit coupling. By doing so, even more simplifcation is permitted in the form of an extremely elementary treatment of spin, basically up or down. As such there are no spinors or Pauli matrices anywhere in this work. Finally, relativistic effects are neglected as well. The introductory chapters provide a brief review of pertinent ideas in classical mechanics and then present the essential elements of the orginal Sommerfield quantum mechanics. This is useful to students as this theory is often used in examples and is interesting historically. These chapters culminate in a detailed chapter on the electron wave functions for the hydrogen atom which includes a table of these functions as well as graphs so the student can spend some time really getting to know them. That's a good thing as they are heavily relied upon through the rest of the book, and this book is filled with useful and helpful tables and figures such as these. Next are two chapters on approximation methods. Time independent perturbation theory and the variational method are emphasized, and both are used heavily and extremely illuminatingly in the remainder of the text. The use of these tools was one of my favorite things about this book. This is an excellent text and I would suggest a student of quantum mechanics read it early, certainly before Dirac. Whether or not it is suitable as a first text on the subject is a different matter. This book provides extremely poor motivation (as in none) for Schordinger's equation, simply introducing it in an entirely postulatory manner. This was a difficult pill for me to swallow pedagocically, but it definitely simplifies the treatment as there is no need to discuss Fourier transforms for instance as is necessary in The Principles of Statistical Mechanics for example. For the serious student of quantum chemistry, this book may well be considered only a meager and dated introduction, but it is excellent nonetheless. And any early stage student of quantum theory should find this book highly profitable reading.
