Dear all,
  Does anybody have experience on how to get standard atomic charges for
some
molecules in the opls/aa force field by using Guassian 98?
  Recently I want to do some study on the beta-difluorine substituted
pyrrole
,but the standard atomic charges for the molecule is absent in the standrad
opls/aa force field parameters.So I want to used the Guassian program to
computed the atomic charges for the molecule,But I haven't any idear how to
perform it.Can anybody help me?Could you write in detail on how to do it.
  Thanks in advance.
  Best wishs.
