Fourier Transform Infrared (FTIR) Spectroscopy is a widely used method for studying the molecular structure and chemical composition of materials. It works by transmitting infrared light through a sample and measuring the light absorbed at different wavelengths, which is caused by the vibrational interaction of chemical bonds with the infrared light. The resulting spectrum provides valuable information on the functional groups, bonding structures, and molecular composition of the material. FTIR is used extensively in various fields, including chemistry, biology, and materials science, to analyze substances and identify compounds.
