  Surfaces and Maps

Electron densities, spin densities, molecular orbitals, electrostatic potentials and local ionization potentials may be displayed as isosurfaces or color mapped on top of isosurfaces. Maps are available with continuous color gradient, or discrete bands.

Surfaces and maps may be displayed as opaque or translucent solids, meshes, or as a series of "dots". Area and volume of a displayed surface may be measured and property value at a selected surface location may be measured and posted to Spartan's spreadsheet.

Accessible surface regions may be optionally highlighted, and an alternate definition of polar surface area (termed polar area) based on the value of the electrostatic potential above and below a user-defined lipophilic range is also provided.

     
  Slices Electron densities, spin densities, molecular orbitals, electrostatic potentials and local ionization potentials may be displayed as contour plots.
     
  Animations Molecular models and associated surfaces, maps and slices for molecules contained within a list may be displayed in sequence. This allows visualizing changes in property throughout a chemical reaction or conformational motion. A "special case", involving motion along the normal mode, is useful for establishing whether a transition state smoothly connects reactants and products. Animations can be saved as QuickTime movie files.
     
  Stereo 3D Molecular models and associated graphics can be displayed in 3D using color filtration techniques or via true unassisted stereo display available from SHARP 3D.
     
  Multiple Molecules As many molecules as desired may be displayed simultaneously on screen, together with any associated graphics.
