Vibrational Spectroscopies and Chemometry for Nondestructive Identification and Differentiation of Painting Binders

Figure 3

FT-NIR (a) and Raman (b) spectra of drying oils. Raman spectra are presented after background subtraction. Star symbols point to some specific spectral features discussed in the text. Symbols for each drying oil are taken from Table 1. The assignments of the FT-NIR and Raman spectra are reported in Tables S5 and S6.
