Fluorescence spectroscopy is a broad subject, and this book covers a wide range of those topics. I often refer to this book when presented with a specific topic that I am not familiar with. The general nature of this book is a virtue. An exhaustive and in-depth approach to a specific topic can be overbearing when an overview is needed. Also, the book is well-organized, well written, straightforward, and concise - yet it does not omit important and relevant information.
