Source data for publication: Resolving the Arrhenius paradox by isochoric analysis of rotational barriers in molecular glasses

This dataset contains experimental dielectric and pressure-volume-temperature (PVT) data for N-(7-[(3-trifluoromethylphenyl)ethynyl]-9,9-dibutyl-9H-fluoren-2-yl)-N,N-diphenylamine measured under various temperature and pressure conditions in the glassy state. The molecule contains a rotating phenylene unit bearing a –CF3 substituent, whose internal rotation gives rise to the dielectric β-relaxation process investigated in the associated study. The data correspond to the figures presented in the associated publication and provide the basis for the reported analysis.
