Subject: reaction field in G92


Dear Netters,

   I would like to use the reaction field SCF facility of Gaussian
92 and I have a question about the input.
   In the manual (pp. 20 & 56) it is advised to enter the SOLVENT
radius and dielectric constant as an input data.  However, in the
original Onsager reaction field model the solvent dielectric constant
 but SOLUTE radius are used as input. Is this just a typo in the
manual and should one use the solvent radius? which units shoud be
used (A or Bohr?).  I would be interested to hear comments/tricks/
critics  from persons who have experience with this option. I am
interested in using water as a solvent.
   
   Thank you in advance for your help,
