The Advantages and Disadvantages of FTIR

Recall from above that an FTIR is a specific type of infrared spectrometer. Thus, FTIRs have advantages and disadvantages compared to other types of infrared instruments above and beyond the advantages and disadvantages of infrared spectroscopy generally, which was discussed above.

The advantages and disadvantages of FTIR over dispersive spectroscopy have been discussed in general [44, 45] and in terms of the RAIRS experiment [4, 41, 40-48]. FTIR instruments hold three formal advantages over dispersive spectrometers. These are briefly outlined below.
