The Pippard relations and their spectroscopic modifications are constructed, and the slope dP/dT is deduced from the Raman frequency shifts in this phase of N2. It is shown that the thermodynamic quantities can be predicted from the Raman frequency shifts, in particular, in the ? phase of solid nitrogen.Englishη phaseRaman frequencySolid nitrogenThermodynamic quantitiesRaman spectroscopyArticle10.1515/htmp-2012-0155
