Overview

Global diabatic potential energy surfaces reveal non-adiabatic effects in B(2p2P) + H2 reaction dynamics, suggesting new insights.

Key Points

  • The aim is to construct global diabatic potential energy surfaces (PESs) for the BH2 system and study the dynamics of the B(2p2P) + H2 reaction.
  • Constructed diabatic PESs using a neural network method based on 11,553 ab initio points.
  • Examined diagonal elements V11, V22, and off-diagonal element V12 of the PESs matrix.
  • Performed both adiabatic and non-adiabatic dynamics calculations based on the constructed PESs.
  • Diagonal elements reasonably describe non-adiabatic processes between electronic states.
  • Off-diagonal element V12 satisfies group symmetry operations.
  • Non-adiabatic effects were found to play a crucial role in the reaction process, with adiabatic results deemed unreliable.
