Two-dimensional homo- and hetero-correlation technique applied to NIR and py-MBMS spectra of wood

Keywords: cellulose, hetero-correlation, homo-correlation, near-infrared spectroscopy (NIR), pyrolysis-molecular beam mass spectrometry (py-MBMS), two-dimensional (2D) correlation spectroscopy

In this work, near infrared (NIR) and pyrolysis-molecular beam mass spectra (MBMS) of loblolly pine (Pinus taeda) were studied by means of generalized two-dimensional correlation spectroscopy in order to assign specific contributions of cellulose in the two spectral domains. Homo- and hetero-correlation techniques were employed to analyze the concentration-dependent spectral variations of cellulose. Specific bands of cellulose were assigned in the NIR and MBMS spectra, and moreover two masses m/z at 114 and 173, commonly assigned to cellulose fragments, were found to not originate from the pyrolysis of cellulose.
