Simplified Molecular Input Line Entry Specification

The Simplified Molecular Input Line Entry Specification, or SMILES for short, is a specification for describing the three-dimensional structure of chemicals using ASCII character strings. With a little bit of practice, these strings can be written, read and understood directly; a number of molecular software packages are able to read or generate SMILES strings.
