title: Enhancement of the accuracy of determination of transverse relaxation time in solution state NMR spectroscopy by using Uhrig's dynamic decoupling sequences.
abstract: Recently, a sequence with a set of non-equidistant π pulses, often referred to as Uhrig's Dynamic Decoupling (UDD) sequence has been proposed which is shown to be more efficient in suppressing the time dependent systematic sources of dephasing originating from a bosonic bath. This work aims to investigate the potential of such non-equidistant sequences for more accurate measurement of the transverse relaxation time (T2) in liquid state NMR. We have shown experimentally that the dynamic decoupling schemes can estimate T2 more accurately than the equidistant pulse sequence by suppressing the dephasing effects of the field noise in the solution state.
