Abstract: We report the results of experimental Raman spectroscopy of donor bone samples (rat, rabbit and human) with varying degrees of mineralisation. Raman spectra are obtained for the Raman bands of 950 – 962 cm^-1 (PO₄)^3-, 1065 – 1070 cm^-1 (CO₃)^2- and 1665 cm^-1 (amide I). In demineralised bone, a sharp (98%) decrease in the intensities of 950 – 962 and 1065 – 1070 cm^-1 bands is observed, which is accompanied by the emergence of the 1079 – 1090 cm^-1 band corresponding to the hydrated amorphous state СО₃^2-.

Keywords: Raman scattering, graft, demineralisation, spectrum.
