Chemical Thesaurus Reaction Chemistry Database Periodic Table

A periodic table front end to the Chemical Thesaurus Reaction Chemistry Database Periodic Table. Clicking on an element gives access to database searches of chemical species and their interactions.

A quote neatly sums up what the ChemThes reaction chemistry database project is trying to achieve:

"The Chemical Thesaurus is a reaction chemistry information system that extends traditional references by providing hyperlinks between related information. The program goes a long way toward meeting its ambitious goal of creating a nonlinear reference for reaction information. With its built-in connections, organizing themes, and multiple ways to sort and view data, The Chemical Thesaurus is much greater than the sum of the data in its database.

"The program does an excellent job of removing the artificial barriers between different subdisciplinary areas of chemistry by presenting a unified vision of inorganic and organic reaction chemistry."
