A different picture emerges for continuum solvent models. At the geometry for the endo-TS included in the ESI 9 with dichloromethane indicated as solvent, the total energy of -823.545644624 Hartree was replicated 20 using G16 in G03 mode as -823.545644658 Hartree, an accuracy typical for quantum mechanical codes and indeed a testament to the ability of ever-changing computer hardware over the period 2010 -2023 to accurately reproduce algorithm-based calculations. The original reported DG obtained by computing thermal corrections to this energy using the values of the calculated vibrational normal modes was quoted as -823.400723 Hartree; no temperature was indicated, but is assumed to be as DG298. 15. The replication value 20 is -823.400161 Hartree, a difference of DDG298.15 = 0.35 kcal/mol. Of more concern was that the gradient norm re-computed under G03 conditions using the quoted ESI coordinates 9 had a root-mean-square (RMS) value of 0.001477267 au, a value >100-folder larger than the threshold noted above for which the values of the atomic coordinates are considered to be converged.
