WebDec 24, 2024 · R0 matches an atom in a ring with size 0 (i.e., not a ring atom) D1 matches an atom with explicitly one bond (so !D1 matches atoms with more than one bond). It's often helpful to use SMARTSview to test patterns. More on RDKit's SMARTS support can be found in the documentation Share Improve this answer Follow answered Dec 26, 2024 at 18:45 WebRDKit uses an atom-based pi-electron counting algorithm to check aromaticity based on Huckel’s Rule. Therefore, this method identifies “true” aromaticity, rather than simply the RMG bond type. The method currently restricts aromaticity to six-membered carbon-only rings. This is a limitation imposed by RMG, and not by RDKit.
