_geom_hbond.distance_DH
Name:_geom_hbond.distance_DH
Aliases:
_geom_hbond_distance_DH
_geom_hbond.dist_DH
Definition:
The set of data items which specify the distance between the three atom sites identified by _geom_hbond.id.
Type: Real
Units: angstroms
The permitted range is 0.0 → infinity
Evaluation method:
with g as geom_hbond l,s = g.atom_site_label_D, g.site_symmetry_D d_pos = SymEquiv(s, _atom_site[l].fract_xyz) d_pos = _atom_sites_Cartn_transform.matrix * d_pos l,s = g.atom_site_label_H,g.site_symmetry_H h_pos = SymEquiv(s, _atom_site[l].fract_xyz) h_pos = _atom_sites_Cartn_transform.matrix * h_pos _geom_hbond.distance_DH = Norm ( h_pos - d_pos )
