The colour centres S 3 in ultramarine blue have been studied by EPR. Measurements of the temperature dependence of the linewidth have shown that the linewidth can be approximated by the formula: B pp D a C bT 7 , which according to the Kronig's theory is describing the two-phonon Raman process of t
