Fourier-transform infrared spectroscopy

Definition

Fourier-transform infrared spectroscopy (FTIR) is an analytical technique used to obtain the infrared spectrum of absorption or emission of a solid, liquid, or gas. This method allows for the identification of molecular structures and functional groups in materials by measuring how they interact with infrared light. FTIR is crucial in various fields, including material science, as it helps researchers characterize polymers and biomaterials, which are essential in tissue engineering scaffolds.
