Propensity for super energy transfer as a function of collision energy for the H + C2H2 system

Supercollisions of NaCl + NaCl on an Accurate Full-Dimensional Potential Energy Surface

“…Energy transfer has long received extensive attention in the experiment and theory, which plays an important role in chemical reaction dynamics, gas-phase kinetics, and chemical deactivations. − In particular, the reactant molecules could be vibrationally or rotationally excited via collisions with the surrounding species, which may change the reactivity of the reactant molecules or promote the reaction. Thus, energy transfer from the initial relative translational energy to molecular internal energy is an important aspect among the various types of energy transfer collisions and considerable efforts have been devoted to the theoretical and experimental investigations. − …”

“…Generally, in most of the collisional energy transfer events, the energy transfer probability decreases exponentially with the amount of energy transferred, which is known as the “exponential law”. − However, in some collisions, the function of the energy transfer probability is not a simple exponential decay function but can present a significant probability for a large amount of energy transfer, which is called supercollision or super energy transfer. , The super energy transfer is related to the complex formation mechanism, which was recently proposed in H + SO 2 , H + CD 4 , H + C 2 H 2 , and H + C 2 H 4 collision systems. − Considering the existence of the (NaCl) 2 complex in the sodium chloride vapor, we are interested in the energy transfer process of the NaCl + NaCl collisions.…”
