  • Detherm database logoDETHERM is one of the world’s largest thermophysical databases. It is available  from the National Chemistry Database service. The service is free to HE Institutions and it can be accessed from a Swansea University IP address. Below is an example of some of the contents:

    DETHERM now contains data from over 100,000 literature documents, equating to over 8,000,000 data rows:
