Written for graduate students and polymer scientists who have a basic knowledge of polymer chemistry and the common spectroscopic methods, but who lack the specific knowledge required to apply the modern techniques of FTIR, Raman, and NMR spectroscopy to the polymer system at hand. Eleven chapters cover the fundamental aspects and experimental applications of the primary spectroscopic methods. The advantages and disadvantages of the various techniques for particular polymer systems are also discussed. The goal of the author is not to make the reader an expert in the field, but rather to provide enough information about the different spectroscopic methods that the reader can determine how the available techniques can be used to solve a particular polymer problem.
