Böhmer, Phys. Rev. Lett. 112, 098301 (2014)] of two supercooled monohydroxy alcohols
close to the glass-transition temperature showed that the Debye peak, thus far mainly
observed in the electrical response, also has a mechanical signature. In this work, we apply
broadband shear-mechanical spectroscopy to a systematic series of octanol structural
isomers, x-methyl-3-heptanol (with x ranging from 2 to 6). We find that the characteristics of …
