Charge Transfer with a Spin. II: A Framework for Diabatization which Localizes Charge and Spin
Alok Kumar, Zhen Tao, Zuxin Jin +2
We investigate a diabatization procedure that localizes charges (in real space) and localizes spins (in spin space) for open-shell systems that exhibit charge transfer in the prese…
