We show that the continuous transmission spectrum and continuous absorption coefficient in the VFIR region (K < 50 cm−1) are distorted by all the weighting functions employed in the process of apodization, when using a Michelson interferometer. We observed that the most common triangular weighting function distorts considerably the FIR spectrum. We found that the weighting function [1- (Δ2/Δ2max)] is more appropriate for smoothing the spectrum.
