  More than 100 years after Debye proposed his model for the dielectric
relaxation of monoalcohols (MA), some fundamental questions about their
dynamics and its relation with the supramolecular structures created by
hydrogen bonding remain not fully understood. The recent detection of the
dynamics of hydrogen-bonded aggregates by techniques other than dielectric
spectroscopy is leading to novel insights and opening new questions. In
particular it was recently reported that the shear response of some MA present
three relaxation components, at variance with their apparent bimodal dielectric
response. We show by mixing an archetype MA with LiCl that both shear and
dielectric measurements are consistent with the presence of three separated
contributions. Results are discussed in the more general context of MAs with
non-exponential slow dielectric relaxations. In particular, we propose the
recently reported third process as the origin of the unusual broadening of the
Debye-like dielectric relaxation of some MAs.
