The diradical formed by functionalizing the yttrium(III)-phthalocyaninato radical with a nitroxide radical, is characterized by an engineered g-tensor asymmetry and a weak exchange coupling. Interestingly, its behavior is reminiscent of a spin qutrit, exhibiting two EPR transitions characterized by different Rabi frequencies and whose amplitudes can be selectively enhanced by proper choice of microwave power or magnetic field.
