dc.description.abstractThe temperature dependence of the damping constant is calculated for some Raman modes in NaNO2 using the soft mode-hard mode coupling model and the energy fluctuation model. The damping constant is fitted to the measured Raman bandwidths of those modes, which is well described by the soft mode-hard mode coupling model. The values of the activation energy are extracted from the damping constant for the Raman modes, which are much greater than k(B)T(C) = 0.04 eV for NaNO2 close to the transition temperature (T-C = 436 K). This is an indication that NaNO2 undergoes an order-disorder phase transition. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheimen_US
