Electric field and Gaussian



  Hi CCLers--
  I was wondering what can be done with electric fields in Gaussian.  I've
  been told that Gaussian can't minimize the geometric coordinates of a
  molecule under an electric field.  But what can it do?  Will it give me
  how an electric field affects the electronic structure of a molecule?
  Can I perform a hessian calculation/find normal modes under an electric
  field?
  Thank you,
  Connie
