Click on a link below to see what it does. You can also type a command in the box below the model to see its effect. The script run in this case was "quartz.cif" {1 1 1};set showunitcell on;moveto 1.0 -989 -17 148 72.7;set perspectivedepth off.
This page can be used to experiment with the prototype.
fractional coordinates
Jmol 10.x.03 introduces a way of specifying fractional coordinates: {1/2, 1/2, 1/2}. A "1" in the denominator is optional: {0.5/, 0.5/, 0.5/}, and in such cases only one slash is necessary: {0.5/, 0.5, 0.5} or {0.5, 0.5, 0.5/}. These may be used in defining the center, in creating draw objects, in defining rotation, spin, and moveto orientation axes, and positions of dipole moments.
Jmol 10.x.04 introduces a new integration of the rotate and spin commands. Either command can be used interchangeably with two parameters -- a total number of degrees to rotate and a number of degrees per second. The only difference is that spin with only one parameter defaults to continuous rotation with the indicated number of degrees per second, while rotate defaults to a single rotation of the specified number of degrees -- exactly the behavior in all previous versions of Jmol.
go ahead and move the structure with the mouse. You will see that it continues to spin around those two points. This is called "internal" or "molecular" spinning.
