adsorbed at various gas pressures (0.01 MPa < p < 0.4 MPa) and T = 298 K
for frequencies [6.10].
Measurements of the capacitance (C) of an electric capacitor allow one
to calculate the relative dielectric permittivity or dielectric constant of the
material included in the capacitor. For plate capacitors we have, cp. Figs 6.1,
