Oak Ridge Thermal Ellipsoid

ORTEP = Oak Ridge Thermal Ellipsoid Plotting Program. With regard to / -values see Sec. 6.2. 

ORTEP is an acronym For Oak Ridge Thermal Ellipsoid Program, a ccropuier program frequently used in structural analysis. The acronym is often used as a short label to indicate a drawing in which ellipsoids indicate the extern of Ihermal motions Of the atoms... 

The "last step" is to use a plotting program to yield a nice picture of atom positions, bonding, thermal vibration ellipsoids, and packing this is an ORTEP plot (Johnson s163 Oak Ridge Thermal Ellipsoid Program) see Fig. 11.73.

A widely used representation for crystallographic data is the ORTEP (Oak Ridge Thermal Ellipsoid Program) plot, as in the example of cyclobutane (Figure 2.4). The ellipsoids provide a measure of the averaged displacements of the atoms in the crystal. ...
