Manual for AIMAll (Version 14.11.23)

Tutorial 8 - Contour Maps

This tutorial shows some ways to generate and display contour maps using AIMStudio.

  1. Open the cyclopropanone.sumviz file generated in Tutorial 1.
     
  2. Select the menu item "Contours->New 2D Grid" to launch a "New 2D Grid" dialog.
  3.           

  4. In the "New 2D Grid" dialog, select the "Browse" button to launch a file open dialog and select the file C:\AIMAll\test\cyclopropanone\cyclopropanone.wfn.
  5. We need to specify a plane for the 2D grid and we can do so by specifying 3 points in the plane.  We are interested in the ring plane so we will use the 3 carbon nuclei for the 3 points.
     
  6. Click the "OK" button in the "New 2D Grid" dialog to begin the AIMExt calculation of the electron density grid.  A console window for AIMExt will briefly appear.
     
  7. In AIMStudio, select the menu item "File->Open in Current Window" to launch a File Open dialog and open the file C:\AIMAll\test\cyclopropanone\cyclopropanon_rho.g2dviz
  8. In the "Maps of 2D Grid Data" dialog, accept the default values for the "Contour Map" tab, uncheck the "Make Relief Map" box in the "Relief Map" tab and then click "OK".
  9.           

  10. Check the menu item "IAS EV Paths->Show IAS EV Paths" and then select the menu item "IAS EV Paths to Show" to show only the IAS EV Paths that lie in the grid plane.
  11. The value of any contour can be displayed at any contour point by simply clicking there.  To remove an existing contour label, simply click near the point again.  To remove all contour labels at once, select the "Contours->Text->Clear" menu item.
  12. Hide the Rho Contour map by unchecking the menu item "Contours->Contour Sets to Show->1. Rho"
     
  13. Repeat step 2-9, except in the "New 2D Grid" dialog, choose "The Laplacian of the Electon Density, DelSqRho" for the Function, use 0.05 for the grid resolution and open the file "C:\AIMAll\test\cyclopropanone\cyclopropanone_delsqrho.g2dviz
     
  14. Check the menu item "Atoms->Nuclear Style->Points" and select the menu item "View->Legend->Header Text..." to make the Legend read "Laplacian of Rho"
  15. Check the menu item "Contours->Negative Style->Solid Paths" and increase the brightness of the negative contour curve colors via "Contours->Negative Color..."
  16. Select "View->Background Color..." to change the background color to white and select "IAS EV Paths->Color..." to darken the color of the IAS EV paths.  Also, change the Title and Legend colors to black via the "View->Title->Font Color..." and "View->Legend->Font Color..." menu items.
