Abstract

Lattice dynamics and bond characteristics in SnCl₄̇5H₂O have been investigated using ³⁵Cl nuclear quadrupole resonance (NQR). Two chemically inequivalent chlorine sites in SnCl₄̇5H₂O were distinguished from the temperature dependences of the NQR frequency and from the spin-lattice (T_1Q) and spin-spin relaxation times (T_2Q). The anomalous temperature dependence of the NQR frequency of one of the two sites was attributed to a thermal weakening of the crystal field from uncoordinated water molecules. In addition, high temperature activated molecular motion was observed.
