Radiation damping effects in NMR spin-lattice relaxation experiments have been studied. After an inversion, a damped spin system recovers to the equilibrium state under the influence of radiation damping rather than through a relaxation process. Therefore, the spin-lattice relaxation time cannot be

β¦ Synopsis
Radiation damping effects on the determination of transverse relaxation times are discussed. Precise measurements in the presence of radiation damping are suggested. In the strong radiation damping case, the spin-spin relaxation time T2 could not be measured by the simple spin-echo technique, but can be determined by an exponential fitting of the CPMG echo amplitudes, while the effective transverse relaxation time Tt can be determined by extrapolating the line widths in a saturation-recovery experiment to an infinitely short recovery time.

It has been found in experiments that the NMR signal intensity of the proton in water increases linearly with the pulse flip angle 0, (Bc T, (where T, is the radiation damping time). Thus for a fairly strong magnetization, the maximum peak height cannot be obtained with a x/2 pulse, but with a pulse
Three commercially produced polymer samples (polyethylene, polypropylene, and polystyrene) have been analyzed in the melt state using proton nuclear magnetic resonance (NMR) T2 relaxation methods using the Carr-Purcell-Meiboom-Gill (CPMG) spin-echo pulse sequence. Samples were run with exposure to a
## Abstract ^1^H NMR imaging has been used to define zones of myocardial infarction (MI), which appear as areas of relatively increased signal intensity (SI). However, zones of decreased SI have been observed within or around the areas of infarction in NMR images acquired at high magnetic fields. T
