| Résumé : |
A comprehensive, multi-instrument Raman spectroscopic study of wet blue bovine leather was performed in order to detect the weak, low frequency, organo-chromium vibrations in chrome tanned leather. Raman scattering spectroscopy is a complementary measurement to infrared absorption spectroscopy. Both types of vibrational spectroscopies theoretically enable the direct measurement of chromium-collagen interactions. Wet blue bovine leather was studied in two forms, slices and powder, by several different instruments (dispersive, Fourier Transform and holographic spectrometer). This paper is an overview of the instrumental and sampling requirements for high quality spectral measurements of this unique sample type. Observed peaks and spectral features are discussed. Implications for protein microstructure and process analysis applications are presented. |
