    "abstract": "An analytical expression has been developed to describe the effects of T2\nrelaxation and diffusing spatially modulated longitudinal spins during the\nsignal build period of an HOMOGENIZED cross peak. Diffusion of the longitudinal\nspins results in a lengthening of the effective dipolar demagnetization time,\ndelaying the re-phasing of coupled anti-phase states in the quantum picture. In\nthe classical picture the unwinding rate of spatially twisted magnetization is\nno longer constant, but decays exponentially with time. The expression is\nexperimentally verified for the HOMOGENIZED spectrum of 100mM TSP in H2O at\n4.7T.\n  More Keywords: magnetic resonance spectroscopy, MRS, intermolecular multiple\nquantum coherence, iMQC, intermolecular zero quantum coherence, iZQC, distant\ndipolar field, DDF",
