Smiles rearrangement in synthetic chemistry bentham science. The simplified molecularinput lineentry system smiles is a code in the form of a line notation that represents the molecular structure of a species using short ascii strings. Smiles is an acronym for simplified molecular input line entry specification. Herein, the smiles notation is explained in the context of tetrahedral chirality centres, which is the most straightforward instance of chirality in organic chemistry.
