Using Born Oppenheimer Molecular dynamics (BOMD) simulations and Path Integral Molecular Dynamics (PIMD) simulations coupled to the Generalized Langevin Equation based thermostat (PIGLET) we have studied the temperature dependent behavior of NQEs on the DPT in form I of TPA. Our findings suggests that NQEs involves a dominant tunnelling DPT mechanism at low temperatures (< 100 K) whereas at room temperature (300 K), it is most probably the zero-point energy fluctuations that increases the shuttling process by decreasing the activation barrier. In both scenarios, as expected, the hydrogen atom shuttles more like a proton rather than a neutral atom. Moreover, we observed that NQEs, in addition to creating neutral tautomers, also create a small but non-negligible amount of charged intermediates at both low and high temperatures. The rest of the manuscript is divided as follows: in Section 2 we provide the details of the BOMD and PIMD simulations.
