✦ Synopsis

The proton NhlR spectrum of NH4PF, at 77 I: remains narrow even under a pressure of 14 kbar. The barrier for PFZ reorientation at 14 kbar is higher than the value at 1 bar. The asymmetry of the t9F spectrum at 77 K increases with pressure. The possibility of inequivalent chemical shifts of the 19F nuclei forming the octahedron around the phosphorus ion is discussed.
