All the calculation options of HSC Chemistry utilize the same databases, and therefore they are an essential part of the program. The enthalpy (H), entropy (S) and heat capacity (C) values of the elements and compounds are saved in the database together with a variety of additional information.
HSC Chemistry can handle two active databases simultaneously, denoted as Own and Main database. The current version of the Main database contains thermochemical data of more than 25 000 species, including pure substances and aqueous species. The Own database is reserved for the data specified by the user. It is empty when the user gets the software, but up to 60000 species can be saved in one Own database. The user may create as many Own database files as he/she likes.
We are continuously collecting new H, S and Cp data and improving old data. If you know of new data sources and you want to share your knowledge, please e-mail the information to us, as we would be extremely interested:
