Relaxation time measurements are an important part of magnetic resonance (MR). They involve the observation of the longitudinal (T1) and transverse (T2) relaxation and, in the case of this work, T2* which is driven by T2. There is great value in T1-T2 and T1-T2* correlation measurements to measure samples such as rock cores, and other solid samples including metal-organic frameworks. 2D relaxation correlation experiments are similar to 2D NMR experiments, the 2D analysis of both methods allows for better differentiation of MR signals.
