THE ROOM-TEMPERATURE DIELECTRIC SPECTRUM OF 2,2-DIMETHYL-1-BUTANOL

The dielectric spectrum of the title substance ('neohexanol') in its p ure liquid state is reported for 293 K up to 71 GHz and, for a restric ted frequency range, also for lower temperatures (down to 253 K). The room temperature spectrum resembles that of alicyclic alcohols, in par ticular cyclopentanol, with respect to spectral shape, main relaxation time and the relation of the latter to viscosity, which similarity ma y be connected with the fact that these alcohols are able to form 'pla stic crystals'.
