## Abstract

This commentary addresses the anomalies in the results reported from the CRESU-SIS experiment at the Institute of Physics of Rennes, France. This experimental setup is dedicated to studying ion-molecule kinetic in the gas phase at very low temperatures using a uniform supersonic flow reactor. A reinterpretation of the latest study performed with this instrument highly suggests a dramatic decrease in flow density upon the injection of neutral reactants. In particular, these concerns can be related to the diffusion effects prevalent in the reported results on the vast majority of the kinetics experiments conducted with a uniform supersonic flow reactor. The scientific community in the field of low-temperature chemical kinetics in uniform supersonic flow would greatly benefit from being aware of and comprehending these highlighted anomalies because the evidence in this commentary calls into question many of the results published to date.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
