The proton NMR spectrum of $NH_4PF_6$ at 77 K remains narrow even under a pressure of 14 kbar. The barrier for $PF_6^-$ reorientation at 14 kbar is higher than the value at 1 bar. The asymmetry of the $^{19}F$ spectrum at 77 K increases with pressure. The possibility of inequivalent chemical shifts of the $^{19}F$ nuclei forming the octahedron around the phosphorus ion is discussed.
