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://server.ccl.net/chemistry/resources/messages/2024/09/06.003-dir/index.html michal bak
