Abstract
The chemical-shift tensors have been determined as a function of temperature on going through the ferroelectric phase transition in a single crystal of KP, and an abrupt change in was found at . The results show that the transition is not driven by an electronic instability but is a pure lattice transition of the order-disorder type, and demonstrate the usefulness of chemical-shift studies of structural phase transitions in solids.
