Thanks Jing and John,

Yes, I was expecting the rotation to use the system's coordinate axes as displayed on the screen.

Thanks again,

  I assume that what is confusing you is that these rotations
are applied relative to the camera/screen coordinate system, not
relative to the molecule's coordinate system. Another subsequent
reply shows how to perform rotations of the molecule itself
using atom selections, if that is actually what you're trying to do.
