Comparison of the isothermal pressure dependences of longitudinal dielectric relaxation times τ|| for a LC system 7CB (a) and structural relaxation times τα for a typical GL system PDE (b) as well as the isothermal pressure dependences of the corresponding activation volumes Vact for 7CB (c) and PDE (d). The values of Vact for PDE have been reported in ref. 22, whereas the values of Vact for 7CB have been calculated herein in the way suggested in ref. 22.
