The q-BWF functions have been applied to the study of the Raman spectra of molybdenite, that is, the molybdenum disulfide, MoS2. Due to good result we obtained in that case, we start trying to apply q-BWFs to other cases, using them to highlight asymmetries and a behavior of the line shape different from the usual Lorentzian or Gaussian profile. For Molybdenite, we used the Raman spectra from RRUFF database . Here we investigate glasses. The spectra that we find in RRUFF are those of CaO-Al2O3-SiO2 systems with Rare Earth Element (REE) oxides.
