Fourier-transform infrared spectroscopy (FTIR)

Fourier-transform infrared spectroscopy (FTIR) is a technique used to identify and analyze materials based on how they absorb infrared light. When a sample is exposed to infrared radiation, it vibrates in response to specific wavelengths. FTIR measures these vibrations, converting the collected data into a spectrum that represents the sample's molecular structure. Each material has a unique spectral fingerprint, allowing scientists to determine its composition and characteristics. This method is widely used in chemistry, biology, and materials science for applications such as quality control, research, and environmental analysis.
