  A detailed dielectric investigation of liquid, supercooled liquid, and glassy
ethanol reveals a third relaxation process, in addition to the two processes
already known. The relaxation time of the newly detected process exhibits
strong deviations from thermally activated behavior. Most important, this
process is the cause of the apparent excess wing, which was claimed to be
present in the dielectric loss spectra of glass-forming ethanol. In addition,
marked deviations of the spectra of ethanol from the scaling proposed by Dixon
and Nagel have been detected.
