Query: Non-rotational mechanism of polarization in alcohols   Chemical polarity governs various mechanical, chemical and thermodynamic
properties of dielectrics. Polar liquids have been amply studied, yet the basic
mechanisms underpinning their dielectric properties remain not fully
understood, as standard models following Debye's phenomenological approach do
not account for quantum effects and cannot aptly reproduce the full
dc-up-to-THz spectral range. Here, using the illustrative case of monohydric
alcohols, we show that deep tunneling and the consequent intermolecular
separation of excess protons and "proton-holes" in the polar liquids govern
their static and dynamic dielectric properties on the same footing. We
performed systematic ultrabroadband (0-10 THz) spectroscopy experiments with
monohydric alcohols of different (0.4-1.6 nm) molecular lengths, and show that
the finite lifetime of molecular species, and the proton-hole correlation
length are the two principle parameters responsible for the dielectric response
of all the studied alcohols across the entire frequency range. Our results
demonstrate that a quantum non-rotational intermolecular mechanism drives the
polarization in alcohols while the rotational mechanism of molecular
polarization plays a secondary role, manifesting itself in the sub-terahertz
region only.
