Nudged elastic band method翻译
Web4 nov. 2024 · The Nudged Elastic Band (NEB) method is a way to find the Minimum Energy Path (MEP) between a set of reactants and products. Some variants, like the Climbing Image (CI-NEB), also specifically find the transition state along this path. WebNudged Elastic Band Climbing Image With this code, it is possible to calculate not only the MEP for the reaction but also the transition state (TS) configuration at the saddle point. …
