The cause of the abnormally high value of the dielectric constant of n-higher alcohols was investigated on the basis of some experimental results. To begin with, the discrepancies between D.C. conductivity and A.C. conductivity were examined in order to clarify the behaviour of the net conduction-current and the absorption-current due to dipole rotation.
Next, the frequency dependency of the dielectric constant in the low frequency region (30 c/sec∼5 kc/sec) was observed and the results were discussed in connexion with Maxwell-Wagner’s formula on the composite dielectric and with Cole’s theory on the conductive dielectric.
Thus, it seems to be reasonable to think that the high value of the dielectric constant of n-higher alcohols is an apparent value due to the higher electrical conductivity of its molecular rotating phase. An idea on the mechanism of the proton transfer in the solid alcohol is presented.
