Methodological framework introduces the SMILES chemical line notation for molecular graphs, enabling standardized digital representation of chemical structures.

Key Points

To introduce the Simplified Molecular Input Line Entry System (SMILES) and establish standardized methodology and syntax rules for encoding chemical structures into compact linear strings.
Formulated a concise syntax based on molecular graph theory and standard chemical valence to represent atoms, bonds, branching structures, and cyclic rings.
Designed a rule-based encoding framework allowing linear ASCII strings to represent complex two-dimensional and three-dimensional molecular connectivity.
Created an intuitive, human-readable chemical language capable of uniquely and compactly representing diverse organic chemical structures.
Provided an efficient computational foundation for automated chemical storage, sub-structure searching, and cross-platform information retrieval.
