## Abstract The reorientation of a pyridinium ion in the paraelectric and antiferroelectric phase of PyHICl~4~ is investigated using ^1^Hο£Ώ^14^N nuclear quadrupole double resonance (NQDR). The ^14^N nuclear quadrupole resonance frequencies are measured. The temperature variations of the principal va
