How to create an isodensity surface colorcoded with the electrostatic potential with gaussian cube files.

    * Add the formcheck keyword to your gaussian input file Now a formatted checkpoint file called 'Test.FChk' will be created

    * Alternatively add the '%chk=jobname.chk' line to your gaussian input file, and convert the binary checkpoint file to a formatted one with the formchk utility:

    formchk jobname.chk jobname.fchk

    * once you have a formatted checkpoint file, create one cube file containing density and one containing the electrostatic potential, you can do this with the gaussians cubegen utility:

    cubegen 0 density jobname.fchk jobname_dens.cube 80

    cubegen 0 potential jobname.fchk jobname_esp.cube 80

    * now start molden without supplying a filename. Go to the density mode by clicking "Dens. Mode", click 'Read Cube' and select 'Gaussian' and supply the filename of the density cube:

    jobname_dens.cube

    * now click the 'Vr' icon and select 'Color Mapped'. I window will pop up. Select "Gaussian Cube" by clicking on the first button under "Select Types:" string and supply the filename of the electrostatic potential cube: jobname_esp.cube Select the type of output you want to generate, currently only "OpenGL" and "VRML2.0" are supported. Specify the contour value for the isodensity surface.

    Click on 'Apply'. Molden will report the maximum and minimum value of the electrostatic potential it encounters on the isodensity surface. You can use these to set the values of the potential associated with the five basic colors.
