Simplified Molecular Input Line Entry System
open-in-new
<p>The Simplified Molecular Input Line Entry System (SMILES) is a specification in the form of a <a href="/facts/Line_notation/sTqbIFmj">line notation</a> for describing the structure of <a href="/facts/Chemical_species/A8BxM3oW">chemical species</a> using short <a href="/facts/ASCII/vGUI33Qu">ASCII</a> <a href="/facts/String_(computer_science)/4ChJu5WS">strings</a>. SMILES strings can be imported by most <a href="/facts/Molecule_editor/0qIez2t8">molecule editors</a> for conversion back into <a href="/facts/Two-dimensional/f4b397W8">two-dimensional</a> drawings or <a href="/facts/Dimension/0ktmUyac">three-dimensional</a> models of the molecules. </p><p>The original SMILES specification was initiated in the 1980s. It has since been modified and extended. In 2007, an <a href="/facts/Open_standard/RGvhGQVI">open standard</a> called OpenSMILES was developed in the <a href="/facts/Open_source/7X9rCdz4">open source</a> chemistry community. </p>
