Graphical Displays:  
  Molecular Models
 Molecular structures may be displayed in one of several styles, from simple wire and ball-and-wire models, to tube and ball-and-spoke models, to space-filling models which depict actual size.

User-defined planes and points may be added to the models, and geometrical parameters (bond lengths, angles, dihedral angles) as well as surface area and volume (of a space-filling model) may be measured.

An arrow may be attached to the model showing sign and direction of the dipole moment.
     
  Biopolymer Models Ribbon displays for polypeptides and polynucleotides. Display large biopolymers in the popular "ribbon" format with customized color based on strand, secondary structure, or residue type.
     
  Surfaces and Maps Electron densities, spin densities, molecular orbitals, and electrostatic potentials may be displayed as isosurfaces or color maps on top of isosurfaces. 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 queried.
     
  Animation Molecular models and associated surfaces and maps for molecules contained within a list may be displayed in sequence, either by manual stepping or by rapid automated stepping ("animation"). This allows visualizing changes in property throughout a chemical reaction or a conformational motion. A special case which involves motion along a normal mode, is useful for establishing whether a transition state smoothly connects reactants and products.
     
  Stereo 3D Molecular models and associated graphics can be displayed in 3D using color filtration techniques.
     
  Multiple Molecules As many molecules as desired may be displayed simultaneously on screen, together with any associated graphics. Molecules may be aligned based on structure similarities.
