What is FTIR Spectroscopy Principles Explained about?

FTIR spectroscopy works by passing infrared light through a Michelson interferometer, which splits the light into two beams that reflect off mirrors and recombine to produce an interference pattern. This interference pattern is recorded as an interferogram, where the optical path difference is plotted against intensity. As a moving mirror changes the optical path length, the interferogram shows how intensities change with path difference. Diffuse reflectance FTIR allows measuring chemicals on surfaces like
