WebIf the point group here is correct, it could indicate that your starting structure had too high symmetry and you should desymmetrize it. Rarely: If the point group here is incorrect (of higher symmetry), then your z-matrix should be reformulated with more symmetry. If you don't care about symmetry, then you could turn symmetry completely off. WebJul 17, 2024 · From: Gorday, Kent M. Date: Mon, 17 Jul 2024 20:20:15 +0000 Gaussian will assign them when you give it the 'new' starting geometry. Assuming you have the checkpoint in your scratch/working directory, just put "geom=check guess=read" in the route and delete the coordinates below.
