Welcome to Atom Foundry maintained by Michael Bromley. There are two databases currently here...
2014 - Jim Mitroy compiled a collection of his research group's polarisability/London/van der Waals/dispersion source-code/data in
The VDWWWW Project
that was not completed due to his untimely death. I was involved in most of this research.
I also have an archive of the entire set of Jim Mitroy Publications.
1998 - I also scraped the Internet Archive for an older set of van der Waals data by Marinescu.
