Fourier transform infrared spectroscopy

Fourier Transform Infrared (FTIR) Spectroscopy is an analytical technique used to identify materials and analyze their molecular composition. It works by passing infrared light through a sample; different chemical bonds absorb specific wavelengths of this light. These absorbance patterns create a spectrum—a molecular "fingerprint." The Fourier transform converts raw data into a clear spectrum quickly and accurately. This spectrum helps scientists determine what types of molecules are present in the sample, making FTIR a valuable tool in chemistry, forensics, pharmaceuticals, and materials science for material identification and analysis.
