CCL:G: POLYRATE + SOLVENT EFFECTS



 Sent to CCL by: Jean Jules FIFEN [julesfifen{}gmail.com]
 As you see, do the computations as you suggested would not help to
 handle rate constants in solvents. You need to undertake geometry and
 frequency computations in solvents. I suggest you to start
 solvent-computations from gas phase geometies.
