Comment on:"Dynamics of glass-forming liquids. XIII.Microwave heating in slow motion"[J. Chem. Phys. 130,194509,(2009)]

TL;DR

This paper critiques a previous study on dielectric hole burning in supercooled liquids, emphasizing the importance of shorter time steps and highlighting inconsistencies in experimental data that hinder theory-experiment comparisons.

Contribution

It demonstrates the necessity of using shorter time steps in analyzing dielectric experiments and points out data inconsistencies affecting theoretical validation.

Findings

Shorter time steps reveal strong oscillations in dielectric data.

Inconsistent experimental data complicate theory comparisons.

Proper analysis methods are crucial for accurate interpretation.

Abstract

We show that the time dependent Dielectric Hole Burning experiments performed on supercooled liquids in the commented paper should be analyzed with a much shorter time step. The results would then exhibit strong short times oscillations, completely ignored in that paper. Also, different data corresponding to the same liquid are inconsistent ones with the others. They impede comparison between theory and experiment.
