ORCA寻找过渡态报错

闲尾Z

问题描述：用ORCA寻找过渡态（虚频） 报错，请问各位老师应该如何解决，下面是out文件中的报错内容预计输入文件的信息

CP-SCF要算很久 可能是這個報錯 記憶體不足
另外是我覺得freq ts 這部分不需要到tzvp
所以我覺得可以用 def2-svp
另外這個有支援rijcosx?  如果有可以考慮加 gridx4
!BP def2-svp tightscf grid4 optTS freq CPCM(water)

ConvForced 1 # Make sure the scf is converge during calculation.
end

%pal

end


%maxcore 5000 # memory per core

%method
Z_MaxIter 50 # The CPSCF interations while calculate actual hessian

换linux版再试，或者少用点核再试
