However, since these are less probable (higher in energy), their occurrences are rare. All in all, these results suggest that at 70 K DPT in the TPA crystal primarily results in formation of L and R tautomers with the system transiently accessing "rare" configurations where there exists pairs of positively and negatively charged TPA molecules along the chain. Upon increasing the temperature to 300 K, we find an enhanced proportion of events in the first quadrant corresponding to the R tautomer suggesting an increase in proton transfer activities. This symmetrizes the shape of the FES in the first and the third quadrant indicating that at this temperature the disorder in the hydrogen bond network is almost complete. Additionally, the spread of the free energy profile decreases (the elbow observed at 70 K softens) along the δ 1 = -δ 2 direction. This implies that at higher temperatures the probability of finding the configurations where both the protons are on the same molecule is diminished.
