WebWith the Bonds method, each of the selected bonds is rotated by some random amount. This normally provides large changes in the conformation of the molecule, and it is a good method for hopping between local minima. For ring systems, the Ringmaker strategy of Still is included in the Bonds method. Web13. máj 2024 · Gaussian can optimize a structure while keeping a geometry parameter (bond length, angle, dihedral) frozen. Bond lengths/angles that are critical for the reaction coordinate (e.g. a forming or breaking bond) should be frozen so that Gaussian does not try to optimize them (i.e. make them at the length of a formed/broken bond).
