Webb11 sep. 2024 · As Dr. Zou said, SMD is constructed over IEFPCM (if I use the right words), at least in Gaussian. I actually got to check it without SMD option (same molecule), and in this case 1) the "e r ror on total polarization charges" is 0.00492 for CPCM and 0.00493 for IEFPCM, so, seems to me, it's all right with CPCM in Gaussian , for all that. http://sobereva.com/327

WebbI would like to use RADII=BONDI with IEFPCM solvation for trans-4-Methylcyclohexanol. I am using for optimization B3LYP/6-31G(d) or B3LYP/6-311+G(2d,p) methods (I tried … Webb1 mars 2024 · Zero-point energy (ZPE) correction was made on the basis of the frequency calculation with RmPW1PW91/6-311G(d,p) on the SCRF/IEFPCM model in CHCl 3. As expected, the DFT calculation for 1a–p confirmed that trans conformers are more stable than cis conformers.

Webb19 maj 2010 · One of my final calculations was to be a QM:MM calculation (1 molecule:200 waters) with IEFPCM (solvent=water). The previous run (ONIOM without PCM) ran fine and converged after a reasonable time. However with PCM and after 168 processor hours, the calculation has not left the first MM stage.
