Comment on the paper entitled Limited surface mobility inhibits stable glass formation for 2-ethyl-1-hexanol, published in J. Chem. Phys. 146, 203317 (2017)

TL;DR

This comment clarifies misconceptions about the applicability of the Coupling Model to 2-ethyl-1-hexanol, addressing previous issues and reaffirming the model's relevance in understanding glass formation.

Contribution

It corrects prior misunderstandings by demonstrating that the identified problems do not hinder the Coupling Model's applicability to the studied glass-forming liquid.

Findings

The issues raised in the original paper are resolved.

The Coupling Model remains valid for 2-ethyl-1-hexanol.

Clarification supports the model's use in glass formation studies.

Abstract

The authors of the paper, Limited surface mobility inhibits stable glass formation for 2-ethyl-1-hexanol, J. Chem. Phys. 146, 203317 (2017), encountered two problems in considering applicability of the Coupling Model. We show in this Comment that these problems do not exist.
