Polarized absorption spectra of sellaite from the Brumado mine, Brazil, in the near infrared
Polarized absorption spectra of sellaite from the Brumado mine, Brazil, were recorded in the region v = 1600‒4000 cm-1 (λ = 6.25‒2.50 μm). Besides weak, non-pleochroic broad bands in the range of the H2O bending and stretching vibrations ‒ evidently caused by liquid inclusions ‒ a sharp pleochroic b...
