The '''simplified molecular input line entry specification''' or '''SMILES''' is a grammar and vocabulary for specifying the structure of a [[pure substance]] using common ordinary teletype-supported characters. David Weininger developed SMILES while at the Environmental Research Laboratory of the [[Environmental Protection Agency]] at Duluth, [[Minnesota]], [[United States]].<ref>"SMILES 1. Introduction and Encoding Rules", Weininger, D., '''J.Chem. Inf. Comput. Sci.''' 1988, 28,31. This is the classic paper.</ref>

SMILES is, in essence, a language for specifying a chemical compound, and is often precise enough to be a unique identifier.<ref>[http://en.wikipedia.org/wiki/Simplified_molecular_input_line_entry_specification SMILES] by [[Wikipedia]]</ref>
