First, systems are often stored in structural formats such as PDB (Protein Data Bank) and XYZ that reduce the available chemical information to only 3D coordinates, element, and, usually, connectivity (ie. which atoms are bonded to each other). Although these formats are sufficient for atom-typed force fields if the monomers can be recognizably matched to atom name-based force field templates, as is typically done for proteins or nucleic acids, specifying chemical information such as bond orders and formal charges of the topology is a fundamental requirement to most cheminformatics operations and necessary for any investigation into novel systems without predefined atom-types. As such, it is necessary for any generalizable workflows to determine sufficient chemical information of polymer systems from incomplete input formats. We define the "chemical information" in this context as specification of chirality, formal charge, and bond-order throughout the molecule. As we will discuss, this chemical information is a necessary requirement for any force field that parameterizes either directly from the molecular graph, such as OpenFF using the SMIRNOFF specification, or indirectly through the definition of atom types based on the chemical structure.
