Foureir Transform Spectroscopy and Its Applicaitons

What is Foureir Transform Spectroscopy?

Fourier Transform Spectroscopy (FTS) is a kind of spectroscopic technique used to build a high-resolution spectrum of the sample by evaluating the brightness of light after it goes across a sample. The method is based on a mathematical instrument known as the Fourier transform, which alter a signal from time to frequency domain.

  • It can be abbreviated as FTS.


How Foureir Transform Spectroscopy works?

  • A light beam is split into two directions by FTS, one of which travels through the sample and the other not.
  • The interference pattern produced by the recombined two beams is then measured.
  • The interference pattern shifts as one of the beams’ travel lengths is changed, and the sample’s spectrum can be recreated using the Fourier transformation.

A method called the Fourier transform torn down a signal into its parts . In FTS, the difference in the path length of two beams which is directly proportional to the frequency of the light find the interference pattern that is formed by the two beams. A Fourier transform can be used to determine the sample’s spectrum on the basis of interference composition.

Application of fourier transform spectroscopy

  • Astronomy, chemical science, and physics are just a few of the scientific disciplines that frequently employ FTS.
  • Because it can give precise details regarding the rotational and vibrational configurations of molecules, it is especially helpful for understanding the characteristics of molecules.
  • As it can provide details about a material’s composition and structure, FTS is frequently employed in the development of fresh materials.
