A system of rigid benzene ring and two variable torsion angles ϕ(C-C-OH) in catechol-like molecular fragments was studied. A scattergam of the two torsion angles taken from the Cambridge Structural Databank is in a good agreement with the potential energy map calculated with the AMBER compatible energy minimizer ORAL. Symmetry operations and point symmetry domains used during the analysis are described in detail. Results are interpreted in accord with the catchment region theory and the structure-correlation principle.
