AbstractThe Raman spectra of 13 different carbohydrates are investigated by a laser Raman spectrometer. It is found the C—H stretching vibrations around 3000 cm−1 is the best region for qualitative analysis of these compounds. All compounds show an O—H stretching vibration around 3370 cm−1 which was not mentioned by earlier works. Excessive background noise appears in many spectra, probably due to their amorphous stuctures.
