High-frequency ESR measurements were made for single crystals of an organic triradical BIPNNBNO having S = 1/2 and S = 1 species within a molecule. [BIPNNBNO=3,5-bis(N-tert-butylaminoxyl)-4'-(1-oxyl-3-oxide-4,4,5, 5-tetramethylimidazolin-2-yl)biphenyl.] The temperature and field dependences of the linewidth and resonance field were studied. The dominant magnetic exchange coupling is discussed and the frustrated spin structure of this compound is suggested.
