I've measured three different ethanol samples in my IR spectrometer, whose spectra are attached (one in absorbance and another in transmittance units). The measurement was made with liquid ethanol with a liquid cell (ZnSe windows). They have no similarities to the spectra you find in the literature (an example was also attached). The background was measured using an empty liquid cell. Any ideas why?
