19F NMR study of phase conversions in a group of perflouro compounds

The purpose of this work was to determine the phase conversions and the nature of the changes in dynamic properties during the simultaneous application of temperature in the 77-2950K range and 10 kbar pressure to perfluorohexane, perfluoroamyltetrahydrofurane, perfluorodiheptyl ether, perfluorodihexyl ether, perfluoro ethers, perfluorooctane with added cyclic ethers, and perfluoroheptane with added perfluoroisoheptane. The nuclear magnetic resonance of the fluorine nuclei was observed with a solid-body radiospectrometer
