Abstract
Proton NMR linewidths and second moments, and spin-lattice relaxation times in the laboratory (12 and 60 MHz) and in rotating frames (H1= 9*10-4 T) were studied for polycrystalline guanidinium nitrate over a temperature range covering three solid phases. An analysis of the experimental results enabled us to reveal a complex cation motion and derive the respective activation parameters. In the low-temperature phase a proton motion in the hydrogen bond has been demonstrated and characterized. A convergence of two reorientational correlation times of the guanidinium cation has been discovered at the first-order phase transition.
