"Two valuable features for both students and instructors are a strong final chapter on Lasers and Laser Spectroscopy, and a set of 17 worked examples…" (Journal of Chemical Education, January 2005) "…a good reference for those interested in basic theories behind general spectroscopic techniques. I welcome its presence in my professional library." (Clinical Chemistry, December 2004)"…this text is well written and the descriptions relating theory to phenomena are clear and well constructed. The book achieves its goal as a well-rounded textbook." (Applied Spectroscopy, August 2004)
