D. Reference spectra
Answer:B
Which of the following has to be computed to determine transmittance and absorbance at various frequencies?
A. Ratio of signal and noise B. Ratio of sample and reference spectra C. Sample spectra D. Reference spectra
Explanation: The ratio of sample and reference spectra needs to be computed to determine transmittance and absorbance. First, reference interferogram is obtained and then sample is obtained.
