Nuclear magnetic resonance (NMR) provides a convenient and noninvasive means for accurately measuring the self-diffusion coefficient of molecules in solution. The theoretical expressions of apparent diffusion rates of MQCs are given and computer simulation based on the method to measure the self-diffusion coefficient by NMR was discussed and the random walk model of particles is used to simulate the apparent diffusion behaviors of intra-molecular and inter-molecular multiple-quantum coherences (MQCs). The results of computer simulation agree well with theoretical predictions.ProjectsupportedbytheNationalNaturalScienceFoundationofChina (10 2 340 70and 10 10 4 0 11)andtheNaturalScienceFoundationofFujianprovince (A0 2 10 0 0 3
