The first book available devoted entirely to Internal Reflection Spectroscopy (ATR)! Internal Reflection Spectroscopy discusses the theory, instrumentation and applications of ATR spectroscopy. It provides the necessary background for the practical spectroscopist to apply the method to particular applications. "...I find Dr. Harrick’s book a delight to read...This is an important book for the infrared spectroscopist and indeed any serious worker in practical optics will be the better for having read it..." - H. A. Willis, Trans. Faraday Soc.
