Modulated structures dictionary (msCIF) version 3.2.1
_atom_site_displace_ortho.axis
Name:_atom_site_displace_ortho.axis
Definition:
A label identifying the displacement component of a given atom
or rigid group that is being parameterized by orthogonalized
functions. a, b and c are the basic lattice vectors of the reference
structure. For composites they refer to the reference structure of
each subsystem. a~1~, a~2~ and a~3~ are defined by the
items belonging to the ATOM_SITES_AXES category, through
_atom_site_displace_ortho.matrix_seq_id.
Type: Code
The data value must be one of the following:
|
x | displacement along the a axis |
|
y | displacement along the b axis |
|
z | displacement along the c axis |
|
a1 | displacement along an arbitrary a1 axis |
|
a2 | displacement along an arbitrary a2 axis |
|
a3 | displacement along an arbitrary a3 axis |
