And you can confirm that Gaussian is indeed working in the state you specify by taking into account the explanation I give you above. (Note: for large molecules, states can be energetically too close, therefore changes in geometry may lose the exited state of interest. buy an empty whiskey barrelWebNov 18, 2024 · maxstep Gaussian keywords Ask Question Asked 4 months ago Modified 4 months ago Viewed 48 times 1 I'm running a Berny optimization and I need to include the keyword maxstep=1.
