WebNov 29, 2000 · In systems where the force along the minimum energy path is large compared to the restoring force perpendicular to the path and when many images of the system are included in the elastic band, kinks can develop and prevent the band from converging to the minimum energy path. WebThe climbing image technique is a modification of the NEBM where the forces of the image with largest energy in the band, are redefined so this image can climb up in energy along the band to get a better estimate of the saddle point energy [1,3]. The image with largest energy is chosen after relaxing the band with the usual NEBM algorithm.
