In this reply, we discuss some aspects of the comments in , 2024, , https://doi.org/10.1039/D3CP05269A, by Grelska, about our work , 2021, , 19537. In this latter work, we have shown for the first time that, at short times below the picosecond range, the uninterrupted hydrogen lifetime probability () is composed of 3 peaks that are universal across many hydrogen bonding systems. By definition, () concerns pairs (dimers) of hydrogen bonded atoms, typically oxygen atoms. The first peak concerns the lifetime of strictly dimers, the second concerns the influence of chain clusters on dimers and the third the influence of their topology. The comment by Grelska contains a confirmation of our findings through similar calculations for other hydrogen bonding liquids. However, this author claims that it is the (first) dimer peak which concerns the topology of clusters, instead of the 3rd as we reported. Our response is that the 3rd peak reflects topology in the sense of branching, hence the presence of trimer bonding in the cluster, while the first peak shows clear species dependence at long times.
