Abstract

We have studied the transition in ammonium chloride (NH4Cl) by means of H1 NMR. In previous reports, the H1 NMR spin-lattice relaxation time (T1) did not show the critical slowing down, whereas the Cl35 NMR spin-lattice relaxation time revealed a sharp transition at the critical temperature. Our measurements of the H1 solid echo decay constant (T2E) and the second moment near the critical temperature manifest the critical slowing down, and the temperature dependence of the T2E is well explained by the dynamic Ising model.
