    "abstract": "Sequences based on the Distant Dipolar Field (DDF) have shown great promise\nfor novel spectroscopy and imaging. Unless spatial variation in the\nlongitudinal magnetization, M_{z}(s), is eliminated by relaxation, diffusion,\nor spoiling techniques by the end of a single repetition, unexpected results\ncan be obtained due to spatial harmonics in the steady state M_{z}^{SS}(s)\nprofile. This is true even in a homogeneous single-component sample. We have\ndeveloped an analytical expression for the M_{z}^{SS}(s) profile that occurs in\nDDF sequences when smearing by diffusion is negligible in the TR period. The\nexpression has been verified by directly imaging the M_{z}^{SS}(s) profile\nafter establishing the steady state. more keywords: magnetic resonance,\nintermolecular multiple quantum coherence, mesoscale structure, iMQC, DDF",
