ORTEP III
Ortep is the Oak Ridge Thermal Ellipsoid Plotting program for molecular display first released in
the early 1970s. ORTEP III was released in 1996 and mounted on the Acorn by
'Fortran Friends'. The main website is URL

Example Plots
- An alpha-helix in stereoscopic projection, Poly-L-aniline,
the structure was published by Elliott and Malcolm in 1959 in
Proc Roy. Soc, London, A249, p30-41 (1959).
The Pauling and Corey right-handed alpha helix repeats after 13 turns
and 47 residues. The thin "vertical" lines between nitrogen and oxygen
atoms indicate a hydrogen bond path
- A proposed model for V-Amylose (stereoscopic projection)
- 2-amino-3-cyano-4,7-diphenyl-5-hydroxy-benzofuran ethanol solvate
(DPQ+) with atoms numbers and bond lengths plotted.
- Cubane - shows thick bonds with perspective
- Cyclobutane plotted in more than one colour
- Magnesium hexaantipyrine perchlorate, shown with the several
molecules needed to fill the unit cell
- A single molecule of Phenyl hydroxyl norboranone
- Co-ordination polyhedra in Potassium perxenate nonahydrate,
a stereo pair of the unit cell is shown
- Tellurium tetrathiourea bifluoride
- Thorium nitrate pentahydrate
- Vitamin B-12 coenzyme (5,6-dimethylbenzimidazolyl-cobamide coenzyme)
- Hydrogen Yttrium oxalate trihydrate
