ChemMantis, [14] the Chemistry Markup And Nomenclature Transformation Integrated System uses algorithms to identify and extract chemical names from documents and web pages and converts the chemical names to chemical structures using name-to-structure conversion algorithms and dictionary look-ups in the ChemSpider database. The result is an ...
Crystal structure visualization can be integrated into a crystallographic database. Alternatively, the crystal structure data are exchanged between the database and the visualization software, preferably using the CIF format. [33] Web-based crystallographic databases can integrate crystal structure visualization capability. [34]
Read and save structures in various chemistry file formats. Determine if one structure is a substructure of another (substructure matching). Determine if two structures are equal (exact matching). Identification of substructures common to structures in a set (maximal common substructure, MCS). Disassemble molecules, splitting into fragments.
Reaxys is a web-based tool for the retrieval of information about chemical compounds and data from published literature, including journals and patents. The information includes chemical compounds, chemical reactions, chemical properties, related bibliographic data, substance data with synthesis planning information, as well as experimental procedures from selected journals and patents.
In organic structural chemistry, the configuration of a double bond can be described with cis and trans, in case it has a simple substitution pattern with only two residues. The position of two residues relative to one another at different points in a ring system or a larger molecule can also be described with cis and trans if the structure's ...
The CAS database is the most comprehensive repository for data on organic compounds. The search tool SciFinder is offered. The Beilstein database contains information on 9.8 million substances, covers the scientific literature from 1771 to the present, and is today accessible via Reaxys. Structures and a large diversity of physical and chemical ...
The CCDC grew out of the activities of the crystallography group led by Olga Kennard OBE FRS in the Department of Organic, Inorganic and Theoretical Chemistry of the University of Cambridge. From 1965, the group began to collect published bibliographic, chemical and crystal structure data for all small molecules studied by X-ray or neutron ...
