Abstract The IR and Raman spectra of a number of sulfate and selenate alums were recorded at room and liquid nitrogen temperature (LNT). At room temperature, the HOH bending vibrations appear as an unsymmetrical, poorly resolved band. When the temperature is lowered, remarkable changes in the number of bands and their shape take place. In the LNT spectra of α alums, a progression of bands could be
