摘要
The titanium content of pyrope garnet can be quantified using the intensity of a Raman band at about 830cm(-1) that is normalized to the 363cm(-1) band using a spectrometer-specific calibration using 10 to 15 chromian pyropes from Bohemia, Czech Republic. An accuracy of 0.025 wt% could be achieved for TiO2 contents between 0.17 and 0.67wt% TiO2 with a Raman spectrometer with a spectral resolution of better than 3.9cm(-1). The technique can be used in petrological and gemmological studies.
