Fourier-transform (FT) Raman spectroscopy and chemometrics are used as a non-destructive means of discriminating dentine from six mammalian species. The spectra are divided into eleven wavenumber regions and the area in each determined. Normalisation was achieved by dividing through by the values fo...
