24. Which of the following statements about the use of Fourier Transform in spectroscopy are correct?
(A) Fourier Transform is not applicable to nuclear magnetic resonance (NMR) spectroscopy because NMR data is already in the frequency domain.
(B) In FTIR spectroscopy, a moving mirror is used in a Michelson interferometer to generate an interferogram from the incoming light.
(C) Fourier Transform Infrared (FTIR) spectroscopy uses an interferometer to collect time-domain (interferogram) data, which is then converted to a frequency-domain spectrum.
(D) Fourier Transform allows simultaneous measurement of all wavelengths, improving signal-to-noise ratio.
(E) The signal-to-noise ratio is irrelevant to the number of measurements.
