Abstract

A theory of Nuclear Magnetic Resonance (NMR) is developed for integer-spin, one-dimensional antiferromagnets, which exhibit the Haldane gap. We consider free boson, free fermion and non-linear sigma model approaches, all of which give similar results. Detailed anisotropy and magnetic field dependence is calculated and compared with experiment.
