I confirmed the structure after geometry optimization. As attached snapshots, I get the much different structure of before and after optimization. I am putting in attachment the obtained snapshots (left:before, right: after). Probably, I think that the molecule connectivities did not keep the initial atoms under simulation. In case of Gaussian program, I confirmed the consistment of structure with before and after optimization. How do I solve this problem? Please advise the method to solve it. regards K.AK[before optimization.png][after optimization.png] 2023年10月10日火曜日 16:21:51 UTC+9 Jürg Hutter: Hi I made some changes to your input: EPS_ISO -> use the default value &MGRID CUTOFF 400 NGRIDS 4 REL_CUTOFF 60 &END MGRID I used the default interaction potential. You probably should use a setting for an isolated molecule (Poisson solver, Periodicity NONE) to get best comparison to QC programs.
