|Abstract:||The aim of this study was to describe the compositional changes in the archaeological specimen using FTIR. Fourier deconvolution was applied in the carbonate (500-650 cm−1), phosphate (900-1200 cm−1), and in the amide region (1700-1600 cm−1). The deconvolution of the spectra in the phosphate region 1200-900 cm−1 reveals six components 960 cm−1, 1010 cm−1, 1020 cm−1, 1030 cm−1, 1110 cm−1 and 1120 cm−1. The bone mineral such as CO32−, PO43− particle, collagen, and organic materials were studied in detail from the infrared spectra. The computed parameters such as collagen development, mineralization index, C/P proportion, crystalline index, and maturing of bone help us in characterizing the bone samples. The Low estimation of C/P proportion resulted in changes in Type B carbonate (PO43−) substitution. The absence of phosphate band ~1100 cm−1 and formation of β sheet structure were observed in the samples studied. Increased level of mineralization resulted in the increased in the crystalline nature of the bone samples. The study indicates the utilization of FTIR using self deconvolution technique which helps in understanding the compositional changes in the archaeological sample.|
