Hello everyone,
Recently, I have encountered some issues in measuring T2 relaxation time. As we all know, compared to controlling echo time and performing Hahn echo experiments sequentially to measure T2, using CPMG pulses to measure T2 is a more efficient method.However, I only know how to use Topspin to process pseudo two-dimensional kinetic data, but I don’t know how to fit the one-dimensional CPMG echo curve that I have collected. Therefore, I would like to ask for everyone’s help.
In addition, I have observed that the T2 time measured by Hahn echo and CPMG echo is inconsistent. Why is this? Here is some additional information, my sample is a lithium-ion battery electrolyte that is impregnated in glass fibers.
Here is how I do it for 1H data acquired with cmpg_T2_1d.
It helps to first set the reference phase with phcor30 in a way that all signal is in one channel.
