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

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 T-2 - T-2 Exchange and T-1 - T-2 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 T-2 - T-2 and T-1 - T-2 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. (C) 2018 Elsevier Inc. All rights reserved.
