(a) Change of THz power spectra with respect to different concentrations of CH3CN gas. (b) Change of absorbance spectrum and the corresponding absorption coefficient spectrum with respect to different concentration. (c) Comparison of the measured absorption coefficient spectrum and the calculated one for the gas sample #3 and (d) residue between them for the gas sample #3.
