Spectrometric Identification of Organic Compounds 7 ed.

This book is very detailed, which is great for chemical analysis. However, it's use as a quick reference is lacking; is doesn't have any overview charts or generalized analysis. It makes it rather difficult to find what you need unless you know EXACTLY what you are looking for, and have time to read through a few pages to look for it. Sadly, this isn't usually the case in a rough chemical analysis.
