ABSTRACT:
A computer-implemented process determines candidate three-dimensional shapes of ring-shaped molecules through an exhaustive search of combinations of torsion angles of the bonds of the ring, given known bond lengths and bond angles for the bonds between atoms of the rings, a range of torsion angles and a resolution. Candidate combinations of the torsion angles are selected according to the range and resolution and coordinates of the atoms of the ring are determined for each candidate combination. It is then determined whether each candidate combination defines a physically possible ring. Indications of such candidate combinations are recorded. Candidate combination may then be selected from those recorded so that coordinates of atoms in candidate repetitive structures may be determined.
