WebThe language SMIRKS is defined for generic reactions. It is a hybrid of SMILES and SMARTS in order to meet the dual needs for a generic reaction: expression of a reaction graph and expression of indirect effects. It is a restricted version of reaction SMARTS involving changes in atom-bond patterns. The rules for SMIRKS are:
