A geometric relationship between four atoms. More...
#include <IMP/atom/charmm_topology.h>
Inheritance diagram for IMP::atom::CHARMMInternalCoordinate:A geometric relationship between four atoms.
The atoms (denoted i,j,k,l here) are uniquely positioned in 3D space relative to each other by means of two distances, two angles, and a dihedral.
A regular internal coordinate stores the distances between ij and kl respectively, and the angles between ijk and jkl.
An improper internal coordinate stores the distances between ik and kl respectively, and the angles between ikj and jkl.
In both cases the dihedral is the angle between the two planes formed by ijk and jkl.
