Introduction to Gas Phase FTIR Spectroscopy
assets.thermofisher.comFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. In infrared (IR) spectroscopy, radiation in the IR region of the electromagnetic spectrum is passed through a gas sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted).
