Figure 3

Comparison of raw and pretreated Raman spectral data. Raman spectra of Acacia microbotrya (green), Corymbia hybrid (blue), and Eucalyptus globulus subspecies maidenii (red). The upper panel (A) shows the untreated spectral data, while the middle (B) and bottom (C) panels show the second derivative, and second derivative + standard normal variate (SNV) spectral transformations, respectively. The x-axis is in wavenumbers, while the y-axis shows the Raman intensity.
