This study is organized as follows. In Section 2, we provide a detailed analysis of the limitations of IDPP and introduce the novel structure-based potential energy to overcome these limitations. We also demonstrate that this potential energy is compatible with our recently developed direct MaxFlux method 9 for reaction path/TS search. Section 3 demonstrates that our proposed potential energy can generate plausible reaction paths even for cases where IDPP provides high-energy paths. Lastly, Section 4 concludes this study.
