Abstract

The study by spectroscopie Raman relave to compound was interpreted and attributed one being based Theory of group and by comparison with others composed. The current studies of the polarised Raman spectra of give evidence that the disorder is indeed present in the ammonium alum. This is best manifested through the appearance of surplus bands in the spectral regions of vibrations of the sulphate anion.
