After this literature search (vdW parameters ?) you could run PyRED at
RED Server Dev.
http://q4md-forcefieldtools.org/REDServer-Development/
You start from a PDB file for your models.
See
http://q4md-forcefieldtools.org/Tutorial/Mini-HowTo-InputFiles.pdf
RESP charges are derived and FF parameters are listed (known &
missing). By using the Re_Fit mode you can resubmit a job, and provide
these listed missing FF parameters using a frcmod.user file.
