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. It works by collecting spectral data at different wavelengths simultaneously, providing detailed information about molecular vibrations and chemical bonds, which is essential in characterizing biomaterials and understanding their interactions with biological tissues.
