Hope this helps,

Kind regards,

>I am interested in optimization of a minimum energy intersystem crossing between S1 and T1 states with MCSCF. The S1 state is calculated using SA2-MCSCF, taking S0 and S1 in averaging, and T1 is calculated as SS-MCSCF, i.e. MCSCF just for the first triplet state.
>I could not find an example in the manual for such a case, therefore I wonder if someone had performed a similar calculation and could share the input. In particular, how to specify that S1 should be computed as SA2-MCSCF, and T1 should be computed as SS-MCSCF, and the multiplicity of the states is different.
