  Weblink 13.4 MOs illustrating s conjugation in an alkene

These MOs show the interaction between the C–C p MO and the C–H s orbitals. (The geometry is slightly different from that shown in Fig. 13.11, so the MOs do not look exactly the same).

  • Click and drag to rotate the structure; shift_click and drag to zoom
  • Select the MO to view using the menu
  • Select the type of surface using the radio buttons
  • Use the check box to display the nodal surface (zero contour - shown as a green mesh)
  • Use the buttons to change the iso-surface value
