Fourier-transform spectroscopy

  "id": "MLC-T-CHM-004621",
  "term": "Fourier-transform spectroscopy",
  "field": "Chemistry",
  "definition": "A spectroscopic technique where an interferogram, representing the signal as a function of optical path difference, is measured and then converted into a spectrum (signal as a function of frequency or wavelength) using a Fourier transform. This method offers advantages in signal-to-noise ratio and speed compared to dispersive spectroscopy. It is commonly applied in infrared (FTIR) and nuclear magnetic resonance (FT-NMR) spectroscopy.",
