NAME¶
Chemistry::OpenSMILES::Aromaticity - Aromaticity handling routines
DESCRIPTION¶
Chemistry::OpenSMILES::Aromaticity encodes some aromaticity handling subroutines for aromatisation and kekulisation. Both implementations are experimental, handle only some specific cases and are neither stable nor bug-free, thus should be used with caution.
METHODS¶
- aromatise( $moiety )
- Mark electron cycles as aromatic.
- kekulise( $moiety )
- Find nonfused even-length aromatic cycles consisting only of B, C, N, P, S and mark them with aliterating single and double bonds.
- electron_cycles( $moiety )
- Find electron cycles according to "Finding Electron Cycles" algorithm from <https://depth-first.com/articles/2021/06/30/writing-aromatic-smiles/>. Use with caution: the implementation is experimental.
