Résumé
The study by FTIR of cassiterites samples, of twelve hydrothermal and pegmatitic spanish deposit shows, on the one hand, that besides the four models of normal vibrations still known this mineral, there hare another two new infrared active vibrations, V5= 700-705 y V6=430-440 cm-1 and on the other hand, that the FTIR spectra of cassiterite vary in form and intensity, but not at the positions of absorption peaks, in function of quantity of impurities, in relation to, at time, with ith its genesis.
