✦ Synopsis

Tcmpcnturc dcpundcnt optical second harmonic generation (SIC) results xc used to monitor the 7O trigonai dcformation of the NW& uctahcdron in fcrroclcctric I.iNbO+ The StXG structural results compare favorably with those obtaincd from conventional (X-my) techniques. The tempcraturc dependence of the spontaneous polarization Ps, calculated vk~ the same trigonal deformation model is consistent with the cxperimcntal observations.
