The mechanism of the ferroelectric transition in KH2PO4-type crystals has been probed using magic angle spinning 31P NMR on single crystals. The higher resolution thus obtained has enabled us to detect a marked change in the 31P isotropic chemical shift around the transition temperature Tc, with a clear jump at Tc. These results are interpreted as evidence that the transition involves a displacive component with electronic instabilities playing a role in the driving mechanism.
