   You need to do a frequency calculation and then you will have all the
 thermodynamic parameters including the free energy, the zero-point energy, etc.

 Dear all,
 I am performing Gaussian calculations using implicit solvation (CPCM).
 Afterwards, I would like to apply thermal corrections from gas phase
 calculations to obtain free energy differences of certain molecules. The
 Gaussian output contains several energy values when using implicit solvation,
 e.g. "After PCM corrections, the SCF energy is  -193.093761350" and
 "Total free energy in solution with all non electrostatic terms".
 Which one would I use to add the correction for free energy?
 Thanks in advance,
 Arnehttp://www.ccl.net/cgi-bin/ccl/send_ccl_messagehttp-:-//www.ccl.net/chemistry/sub_unsub.shtmlhttp-:-//www.ccl.net/spammers.txt
