Fourier-transform spectroscopy is a measurement technique based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the electromagnetic radiation or other type of radiation. It can be applied to a variety of types of spectroscopy including optical spectroscopy, infrared spectroscopy (FTIR, FT-NIRS), nuclear magnetic resonance (NMR) and magnetic resonance spectroscopic imaging (MRSI), mass spectrometry and electron spin resonance spectroscopy
Fourier-transform infrared spectroscopy (FTIR) is used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. Unlike conventional Infrared spectroscopy, an FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range.
ICAM equipment includes:
- Nicolet 5700 at Imperial College London. A Pyrolysis/ATR-Fourier Transform Infrared system that provides information about the chemical bonds present in target materials. Attenuated Total Reflectance allows the analysis of solid or liquid materials, while pyrolysis evaporates, desorbs and thermally generates gas mixtures.
- Perkin Elmer Spectrum One FT-IR and Perkin Elmer Spotlight 400 FT-IR at the University of Cambridge.
