Automation of the Peak Fitting Method in Bone FTIR Microspectroscopy Spectrum Analysis: Human and Mice Bone Study

Figure 7

Original spectrum in the ν4PO₄ area (dark blue line) recovered by the Gaussian sum fitting (dotted-black line) and the 4 individual peaks beneath (full lines). The peak used to compute the Crystallinity parameter is 604 cm⁻¹ (yellow line).
