DOI: 10.1016/j.jmr.2017.12.012
Abstract: Delayed-acquisition, which is a common technique for improving spectral resolution in Fourier transform based spectroscopies, typically relies upon differences in T2 relaxation rates that are often due to underlying differences in dynamics and/or complexities of… read more here.
