Both the intensities and frequencies of the TO and LO modes of sphalerite are approximately independent of Fe concentration. However, the substitution of Zn by Fe results in five additional bands with frequencies between the TO (271cm−1) and LO (350cm−1) modes. Three of these bands are attributed to resonance modes (i.e. Y 1, Y 2 and Y 3 modes). The fourth band (B mode) is assigned to a breathing mode of the nearest-neighbor sulfur atoms around the Fe atoms. The band at 337cm−1 is attributed to the presence of Fe3+. The excellent correlations between the normalized intensities of these five different modes and x Fe show that these modes depend on Fe-content. Another extra mode at 287cm−1 is assigned to the presence of Cd in sphalerite.
