Who did I plagarize this stuff from? Perhaps plagarize is a bit too harsh ... filtered would probably be more appropriate. I find that usually no one source provides all of the details ... they either leave them out on the assumption that you will just know or they say 'it can be shown that' but don't say where. I have found each of these books to be very good at at least one topic. The format is my own .. I figure that if you are reading these pages you are smart enough to take this information and look for it on your own. That's what I did. In no particular order of preference:
 J.A. Weil (department of chemistry, U of Sask.!) and J.R. Bolton, Electron Paramagnetic Resonance 2nd edition, 2007. This book gives a pretty good discussion of the ladder operator method for obtaining the eigenfunctions of J_{z} and J^{2}. Most (but not all) of the angular momentum material is based on this discussion. I should say that if you are looking at the 1st edition of this book there are some confusing errors in the appendix on ladder operators and angular momentum. They are fixed up in the second edition.
 J.P. Lowe and K. A. Peterson, Quantum Chemistry. This is a very good allround introduction to quantum mechanics ... not too heavy on the math (although there is certainly lots of it, no way to avoid it!). No nmr but useful for understanding nmr.
 I.N. Levine,Quantum Chemistry. Another good introduction to quantum chemistry. This one has two approaches to obtaining the eigenvalues of J_{z} and J^{2}, the ladder operator method that I have used here and the fullblown differential calculus method. Again, no nmr but useful for gaining some understanding.
 M.H. Levitt,Spin Dynamics. A nice intro to nmr spectroscopy from a physics point of view and also, a productoperator/matrix discussion that is quite lucid (as it probably should be since he was one of the authors of the seminal product operator paper). The only book that I have seen that gives a readable description of the mechanism of the attaining of an equilibrium of an ensemble of spins in a magnetic field. This book is like that treasure chest of toys in your grandparents' attic. Lots of interesting and neat things. Thank you, Professor Levitt!
 Richards, Sears, Weir, Zemansky,Modern University Physics. My first university physics text and still the one that I refer back to for basic stuff ... a bit dated though ... uses pounds for force units!
 C.P. Slichter, Principles of Magnetic Resonance. This is one of the classic nmr texts. Not for the faintofheart, though .. lots of math.
 P.L. Corio, Structure of HighResolution NMR Spectra. The only book that I have found that gives a detailed description of the mathematics of the rotating frame idea.
 J. Keeler, Understanding NMR Spectroscopy. This is just a fabulous book!! Thank you so much, professor Keeler. Many things about nmr spectroscopy that were a mystery to me were cleared up after reading this book. I most highly recommend it.
 J.K.M. Sanders and B.K. Hunter, Modern NMR Spectroscopy: a guide for chemists. This is a nice gentle introduction to nmr spectroscopy for the uninitiated. Not a lot of math and what there is, is just simple algebra. Lots of pictures and heavy use of the vector model. A nice case example for the structure analysis of sucrose octaacetate. Convinced me to use sucrose octaacetate as a teaching sample. Great for demonstrating lots of things.
 M. Goldman, Quantum Description of HighResolution NMR in Liquids Another approach to nmr via quantum mechanics. Nice to have different viewpoints ... I find it can clear up questions that I have when reading a text.
R.J. Smith, Electronics: circuits and devices. Contains a discussion of the analysis of AC circuits which is useful for understanding the tuning and matching procedures.
