We have performed magnetic resonance measurements on the Ising-like Heisenberg triangular antiferromagnet CsNiBr3 in the lowest ordered phase. Remarkable deviations from the conventional 6-sublattice model were observed for some ESR eigen modes. We show that these deviations are removed by introducing a diagonal interchain interaction. We also investigate the exchange and anisotropy parameters of this compound.
