Hello,
I want to do CCSDTQ(P) calculations by both the restricted and unrestricted methods.
I am using:
mrcc,method=RCC(n-1)(n),excitation=5,restart=1
and
mrcc,method=CC(n-1)(n),excitation=5,restart=1
but I am not sure what else I should add so that the program considers (P) as well as CCSDTQ.
Could you please help. Thank you.
