Different types of Ethanol can be directly identfied by the value of the Raman shirt of the signal. Optical … Webb23 okt. 2024 · The identical procedure was applied to the Raman spectra of gaseous ethanol (C 2 H 5 OH), resulting in a ratio ranging from 1.0 (518 K) to 0.5905 (882 K) between both normalized cross sections (CH 2 O/C 2 H 5 OH). This type of crosstalk has to be accounted for in future data evaluation strategies for renewable hydrocarbon fuels.
