摘要：
Five different celluloses are studied with FT-IR, FT-Raman and near-infrared (NIR) spectrometry, and the fingerprint region of the spectra is assigned. identification of each of the five celluloses is possible with each of the three vibrational methods. Four different batches of hydroxyethyl cellulose yield very similar spectra with each of the three methods. The methods are compared with respect to their capability to discriminate between celluloses and batches, and with respect to ease and feasibility of sample preparation.
