Fourier Transform IR spectroscopy (FTIR) - How it works?

What is FTIR and Michelson interferometer? It is one of the non-dispersive IR technique which is more accurate and precise over conventional dispersive IR spectra. Here Fourier Transformation is a mathematical conversion of time domain into frequency domain.

Clear, now easy to understand, thank you.

The fact is at a particular position of the scanning mirror or scan time, one particular wavelength gets into constructive interference giving rise max intensity at that wavelength.

Excellent explanation, simple to understanding, can you share it as powerpoint pls.

Very helpful sir👍👍easy to understand. Thank you

Please say " big stepor underground methods" once

[alexandreleonardo]

This is all very clear. Thank you. Just one question. If using two different bacteria to test for biodegradation, can the peaks differ depending of the organism used? The peaks i got after incubation with Pseudomonas have a lower absorbance than the peaks obtained using ideonella. The compound is neat PET.

Can you tell us why we are measuring the position of movable mirror .

[devanggondaleeya]

Why need to convert time domain spectra in to frequency domain ?

[marthareddy]

Why you are saying everytime one particular wavelength will pass through the sample ? In fact all the wavelengths pass through the sample all the time.

[educationhub]

Why transmittance is plotted not absorbance in IR spectra ??? Please answer

Are you Paresh Patel sir, from surat?
