Abstract
The H1-N15 double resonance rates in powders of NH4NO3 and (NH4)2SO were investigated as a function of the rotating field H1 magnituae and N15 spins concentration, The cross-relaxation dynamics at the sites of NH +4 and NO −2 groups in NH4NO3 were investigated separately by selective enrichment. The cross-relaxation rates exhibit an exponential dependence on H1. No limitation of the cross-relaxation by spin diffusion was observed.
