Description

Reading and SDF file created with structures optimized by MOPAC includes properties such as the dipole moment. When these are read the units of the properties -- which are not carried in the SDF file and would not be handled by the reader if they were -- are not added when the property is created. The property has the form of 'dipole moment#MOPAC#PM6-ORG' which is not found in the standard properties due to the added attributes of the code and model.
