The study provides new insights into the OH stretching vibrations of serpentine species (lizardite, chrysotile, antigorite) encountered in veins of peridotite. A combination of infrared spectroscopy in the mid-infrared and near-infrared ranges and Raman spectroscopy enabled us to interpret most of the observed bands in the fundamental and first overtone regions of the spectra and to propose consistent spectral decomposition and assignment of the OH stretching bands for the serpentine species.
