WebAug 1, 2024 · This step is necessary for any calculation, without it the Gaussian crashes. For well behaved molecules, as the prostaglandines (organics) most probably are, the solution should be found fast (<30 SCF cycles). It also does not matter which converger you choose, i.e. QC or DIIS.

"WebAug 26, 2024 · Planarity is a very important structural character of molecules, which is closely related to many molecular properties. Unfortunately, there is currently no simple, universal, and robust way to measure molecular planarity. In order to fill this evident gap, we propose two metrics of molecular planarity, namely molecular planarity parameter (MPP) … " - Gaussian acc2e
