Webb31 okt. 2003 · Natural magnetite (Fe 3 O 4) in the form of single crystal and powder was studied by laser Raman spectroscopy at various laser powers. The correlations between the power of the excitation laser, the temperature of the sampled spot and the degree of oxidation of magnetite were accurately established. Webbthe Raman spectrum peaks of magnetite were investigated, where from certain vibrational modes, peak 670 cm-1 was identified as a band characteristic. Shebanova conducted some experiments using various powers of the laser Raman spectrum for magnetite. And they concluded that above some critical value of the laser power, the Raman spectra … does yoni pearls cause bleeding
