I want to optimize the same fragment, but putting one of the vanadium centres with an oxidation state of (V), in which case it will present non unpaired electrons (d0 external configuration). Anybody knows which keyword is useful to do this ? Is not the same case in which I can use de SpinFlip keyword, which works to change the spin of the electron of the centre of interest. Thank you in advance Best regards Karina
