Electron-density isosurface

WebThe electron density surface onto which the potential is mapped can be calculated at different density levels. The suggested value in MOLDEN, 0.02 is appropriate for the analysis of non-covalent interactions as it roughly corresponds to the surface that two non-reacting molecules can approach. Larger values, e.g. 0.05 may be useful if one is ... WebBy default, an isosurface for the ESP is displayed in the Workspace. To change this to a map of the ESP onto the electron density surface: Select the electron density and deselect the ESP in the In column (V column in 2013-3 and earlier). Click Display Options. The Display Options dialog box opens. Select Map values from volume data.
