Simultaneous acquisition for T2-T2 Exchange and T1-T2 correlation NMR experiments

[Display omitted] •New method to perform simultaneous T2-T2 Exchange and T1-T2 correlation experiments.•The fast T2-Filtered T2-T2 Exchange method is demonstrated for Indiana Limestone.•Log-normal fitting is used to analyze T2 distributions and construct Exchange curves. The NMR measurements of longitudinal and transverse relaxation times and its multidimensional correlations provide useful information about molecular dynamics. However, these experiments are very time-consuming, and many researchers proposed faster experiments to reduce this issue. This paper presents a new way to simultaneously perform T2-T2 Exchange and T1-T2 correlation experiments by taking the advantage of the storage time and the two steps phase cycling used for running the relaxation exchange experiment. The data corresponding to each step is either summed or subtracted to produce the T2-T2 and T1-T2 data, enhancing the information obtained while maintaining the experiment duration. Comparing the results from this technique with traditional NMR experiments it was possible to validate the method.
