Ortep-3 for Windows is a MS-Windows version of the current release of ORTEP-III (1.0.3), which incorporates a Graphical User Interface (GUI) to make production of thermal ellipsoid plots much easier. Most of the commonly used features of ORTEP-III are directly available from the GUI. Loading a coordinate file will result in a default view of the molecule immediately, and no knowledge of the inner workings of ORTEP is required to produce excellent publication quality output.
