A structure can be aligned in a plane defined by a sequence of
three non-collinear atoms.
Select the (View-->Three atoms plane...) menu
and then clisk three atoms in sequence. After the sequence 1-2-3 of the selected
atoms is terminated the whole structure will be aligned in the plane defined by
the 1-2-3 sequence.
The first selected atom 1 will assume the coordinates: X:-d(1,2);
Y:0.0; Z:0.0 whereas the second atom 2 will be put at the origin, i.e. X:0.0;
Y:0.0; Z:0.0.
The following pictures show two different choices for the 1-2-3
sequence
Best plane through atoms
By selecting the (View-->Best plane) menu the
whole structure will be aligned in the best geometrical plane crossing as many
atoms as possible.
This is useful to quickly make the best view of a structure
