Substituted rings can be written with the branching point in the ring as illustrated by the SMILES COc(c1)cccc1C#N (see depiction) and COc(cc1)ccc1C#N (see depiction) which encode the 3 and 4-cyanoanisole isomers.
Os aneis substituídos poden escribirse co punto de ramificación no anel como se ilustra no SMILES COc(c1)cccc1C#N (ver imaxe) e COc(cc1)ccc1C#N (ver imaxe), que codifican os isómeros 3 e 4-cianoanisol.
