: I did a caspt2 calculation of an Er(III) complex. It didn't converge. Then I did the same calculation with a shift=0.4 and it converged. I want the results without that shift.
: If I repeat the calculation without the shift using the information of the calculation with the shift, will it converge? What do I need (files from the calculation with the shift) to do the new calculation?
What do you mean with " I want the results without that shift."? If the shift is needed to make it converge, you can't do the calculation without the shift...
Alternatively you can use an imaginary shift.
