Fourier transform infrared spectroscopy, or FTIR, is a vibrational spectroscopy method which is based upon the measurement of specific frequencies which occur between chemical bonds in a given material. Interestingly, as materials may be unique in chemical nature, so are the infrared spectra which they yield, resulting in a unique “fingerprint” for a given material. As such, this makes FTIR a very resourceful tool for such things as:
