COSMObase, COSMObaseIL, COSMObaseFF

The COSMO databases are high quality collections of pre-calculated compound information needed for COSMO-RS calculations. They include databases on the quantum chemical levels supported by COSMOtherm. Each compound is represented by a set of COSMO (σ-surface information) and energy (gas phase energy) files and additional files for physical compound data. Just add the databases to your COSMOthermX settings and use the compounds for your research inside the graphical user interface.

COSMObase

COSMObase is the flagship of the COSMO databases. It includes almost all common solvents, ranging from small molecules to large and complex substances, covering substance classes with all kinds of functional groups (e.g. hydrocarbons, alcohols, ethers, carbonyls, acids, esters, amines, amides, nitro compounds, heterocycles, halogenated compounds, and many more). 

COSMObaseIL

Discover the world of ionic liquids.

COSMObaseIL is a collection of typical ionic liquid anions and cations. The current database contains 421 cations and 109 anions that can be independently combined to form a huge set of potential ionic liquids.

COSMObaseFF

As a special purpose database the COSMObaseFF contains over 2000 flavors and fragrances. The COSMObaseFF is the ideal add-on for consumer goods or fragrance companies.
