Experimental and computed (quantum mechanics) thermochemical data for a selected set of gas-phase atoms and small molecules. Tools for comparing experimental and computational ideal-gas thermochemical properties
A free database of chemistry structures and their associated information. To draw and search on a structure or substructure, click “Structure search,” then click the pencil inside the diagram, then select “Draw or Edit”
PubChem Structure Search allows the PubChem Compound Database to be to be queried by chemical structure or chemical structure pattern. The PubChem Sketcher allows a query to be drawn manually. Users may also specify the structural query input by PubChem Compound Identifier (CID) , SMILES , SMARTS , InChI , Molecular Formula , or by upload of a supported structure file format.
As part of a broader NLM reorganization, most of NLM's toxicology information services have been integrated into other NLM products and services. Links to these products and services can be found on this page.
