You will likely be best served contacting them to see if you can have 
access to their .itp files.

If you don't succeed with the above, then you'll likely need to do your 
own legwork, looking at the functional forms implemented in parmbsc0 and 
available in GROMACS (see manual).

Understanding of parts of chapters 4 and 5 of the manual will be 
required either way.
