Chemically Modified Surfaces in Science and Industry, Vol. 2 Book

As the description promises, it provides an in-depth look at how FTIR works, without launching into detailed technical explanations of how to do the transforms (interesting, but not applicable to the text in question). Information is presented in a way that is clear and easy to follow (as I would expect from the CRC press!), and the explanations are simple enough that even those that are unfamiliar with how FTIR works can glean much from the text. It's not the first book I would recommend for those interested in FTIR, but it's a great resource for those working in the lab who need to look something up quickly.
