Abstract
Magnetic resonance experiments of the S = 1 Haldane gap material (CH3)4NNi(NO2)3 (TMNIN) have been performed in the frequency range 9-115GHz in magnetic fields up to 8 T. Resonance absorptions associated with the transitions between the ground state and the lowest excited state have been observed below about 5 K. The frequency vs. field relations of the resonances provide a gap parameter Eg ∼ 3K.
