Figure 5. Background correction procedures using the spline interpolation. (A) Experimental PM IRRAS spectrum, points a, b, c, d, and e are used to construct the spline. (B) Experimental spectrum (the solid line) with the baseline (the dashed line) constructed by the spline interpolation. (C) Spectrum after the baseline subtraction. (D) Absorption spectrum of the same lipid molecule measured by the transmission method. (E) Experimental spectrum (the solid line) with the corrected position of the point c and the new baseline (the dashed line). (F) Spectrum of the sample after subtraction of the baseline in Figure 5E. Reprinted with permission from Ref. [10]. Copyright 2006 University of Guelph.
