Fig. 5. (A) Representative MIR spectra of forensic and archaeological bone samples with the corresponding C.I. and CO3/PO4 value. 2-D and 3-D Score plots of MIR spectra in the region of 1700 cm–1 to 550 cm–1 (B and C). For the differentiation between forensic and archaeological bone samples for each bone sample 30 spectra were selected from degradation free regions. Each data point represents one spectrum of the respective (colour coded) bone sample.
