Each technique is covered separately in its own chapter and subsequently used in combination with the other techniques to provide more detail regarding the structure of unknowns. The strength of infrared spectroscopy is in the determination of functional groups. This point comes across loud and clear in the first chapter. No discussion is included on how the technique may be used to determine such things as the substitution pattern of simple aromatics from overtone patterns or how to tell if an alcohol is primary, secondary, or tertiary. It seems that a reference to tables where one can find such information might be appropriate.
Mass spectrometry is covered next.
I found this section and all the mass spectra that follow to need some work. It was pointed out that the number of carbons in a compound could be determined by comparing the relative size of significant peaks with those of one mass unit larger. This is valuable information. A useful addition to these spectra would be the inclusion of a table with the relative abundance data. I also found the font size used on these spectra to be too small.
