Calculation of quasi-diabatic states within the DFT/MRCI(2) framework: the QD-DFT/MRCI(2) method [PDF]

open access: yes
We describe a procedure for the calculation of quasi-diabatic states within the recently introduced DFT/MRCI(2) framework [J. Chem. Phys., 157, 164103 (2022)]. Based on an effective Hamiltonian formalism, the proposed procedure, which we term QD-DFT/MRCI(
