Although these models are provided as "freeware", in fairness to the developers, the funding agencies and partners, and to all users, they are copyright. License agreements are accessible through the individual model descriptions.

Databases within the models are not intended as an authoritative information source and all physical chemical properties should be verified by the user. Users should be especially careful about the temperature dependence of physical chemical properties.

From time to time we upgrade our models to correct any problems or errors and to reflect improvements in scientific knowledge. Check this page regularly for updates.

Thank you for your cooperation and your interest in our models.
