A conformation analysis device and analysis method with which discrimination can be achieved even if there is a subtle difference in a conformational structure, a given molecule can be processed in a unified manner, and large-scale computer processing can be performed, and a conformational notation device and notation method with which even in the case where a conformation cannot be uniquely determined if a rule in accordance with the IUPAC Nomenclature is followed, the conformation can be uniquely notated, a given molecule can be processed in a unified manner, and large-scale computer processing can be performed, are provided. In one embodiment of the invention, a processing section receives an input of a chemical structural formula of a compound to be analyzed, puts a predetermined code indicating a dihedral angle to each chemical binding site based on the received chemical structural formula, extracts an encoded conformational notation of interest with respect to a structure capable of uniquely determining a conformation with one conformational notation, and stores the extracted encoded conformational notation in a storage section. Then, the processing section creates a molecular model based on the extracted encoded conformational notation, performs geometry optimization and frequency calculation for the created molecular model, determines a geometry optimized structure and a physical property value of the geometry optimized structure, extracts the encoded conformational notation from the storage section, and performs a homology analysis based on the notation.
