Nmr diffusion coefficient study of steroid cyclodextrin inclusion complexes

LED stands for longitudinal encode-decode or "longitudinal eddy current delay" experiment. The LED experiment is an evolutionary improvement of the PFGSTE (stimulated echo: 90 o -τ PFG -90 o -T-90 o -τ PFG -acquire) experiment proposed by Tanner in 1970[ 2 ]. In LED experiments[ 3 ] magnetization is stored along the z-axis during most of the pulse sequence, so T1 relaxation is predominant. Since in macromolecules the T1 relaxation is slower than the T2 relaxation , the LED experiment is better suited to the measurement of D s of slower diffusing molecules where longer "diffusion delay" is required to detect attenuation of the signal.
