The simplified molecular-input line-entry system (SMILES) is a specification in the form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three … See more The original SMILES specification was initiated by David Weininger at the USEPA Mid-Continent Ecology Division Laboratory in Duluth in the 1980s. Acknowledged for their parts in the early development were "Gilman Veith and … See more The term SMILES refers to a line notation for encoding molecular structures and specific instances should strictly be called SMILES strings. However, the term SMILES is also commonly used to refer to both a single SMILES string and a number of SMILES strings; … See more Atoms Atoms are represented by the standard abbreviation of the chemical elements, in square brackets, … See more SMARTS is a line notation for specification of substructural patterns in molecules. While it uses many of the same symbols as SMILES, it also allows specification of wildcard atoms … See more In terms of a graph-based computational procedure, SMILES is a string obtained by printing the symbol nodes encountered in a See more From the view point of a formal language theory, SMILES is a word. A SMILES is parsable with a context-free parser. The use of this representation has been in the prediction of biochemical properties (incl. toxicity and biodegradability) based on the main principle of … See more SMILES can be converted back to two-dimensional representations using structure diagram generation (SDG) algorithms. This conversion is not always unambiguous. Conversion to three-dimensional representation is achieved by energy … See more
