Description
After a few initial chapters on the basics of Mathematica, the logic of this book is controlled by group theory. The book has three major parts. Part I begins with the most elementary symmetry concepts, showing how to express them in terms of matrices and permutations, before moving on to the construction of mathematical groups. In Part II, mathematical group theory is presented with motivating questions and experiments first, and theorems that answer those questions second. In Part III, the projection operators that flow from the Great Orthogonality are automated and applied to chemical and spectroscopic problems, which are now seen to fall within a unified intellectual framework. Intended for students of chemistry and molecular physics, the book may be read either independently or on a computer screen with Mathematica running behind it. The included CD-ROM presents the entire content of the book plus interactive examples using Mathematica notebooks for problem-solving and learning.
