Web11 Jun 2024 · Sorted by: 8. SMILES doesn't define a particular order in which the atoms show up in the string. Hence the position in the molecule where software starts printing will determine the string. E.g. for CO2: Ketcher prints C (=O)=O (starts with C and considers one of the O's a branch) MarvinJS prints O=C=O (starts iteration with O, hence no branching) Web2 Oct 2012 · The mol2chemfig program introduced here allows the conversion of molecules specified in molfile or SMILES format to the TE X-compatible format defined by the chemfig package.
