Abstract
The monohydroxy alcohol 5-methyl-3-heptanol is studied using rheology at ambient pressure and using dielectric spectroscopy at elevated pressures up to 1.03 GPa. Both experimental techniques reveal that the relaxational behavior of this liquid is intermediate between those that show a large Debye process, such as 2-ethyl-1-hexanol, or a small Debye-like feature, such as 4-methyl-3-heptanol, with which comparisons are made. Various phenomenological approaches assigning a time scale for the rheological signature of supramolecular dynamics in monohydroxy alcohols are discussed.

Notes
Here, we considered an additive approach G ∞ = G ∞,supra + G ∞,α similar to the one expressed by Eq. 8.8.6 in [48]
Instead of a Cole–Cole, also the Cole–Davidson function and generalized approaches were tested. However, the Cole–Cole function gave consistently the most reliable results in particular also for the 265 K isotherm. The α was treated as a free parameter and was found typically found in the range from 0.4 to 0.8.
Also, 2M3H conforms to this trend, see ref. 36.
See Table V and Eq. 1 in ref. 20.
In ref. 25, it was emphasized that particularly for g K values smaller than about unity, their numerical values can sensitively depend on the choice of ε ∞.
See Table 2 in ref. 44
