When the inhomogeneity of the static magnetic field approaches or exceeds the strength of the RF field, the magnetization has contributions from different coherence pathways. The diffusion or relaxation induced decay of the signal amplitude is in general nonexponential, even if the sample has single relaxation times T1, T2 and a single diffusion coefficient D. In addition, the shape of the echo depends on diffusion and relaxation. It is possible to separate contributions from different coherence pathways by phase cycling of the RF pulses. The general analysis is tested on stray field measurements using two different pulse sequences. We find excellent agreement between measurements and calculations. The inversion recovery sequence is used to study the relaxation effects. We demonstrate two different approaches of data analysis to extract the relaxation time T1. Finite pulse width effects on the timing of the echo formation are also studied. Diffusion effects are analyzed using the Carr-Purcell-Meiboom-Gill sequence. In a stray field of a constant gradient g, we find that unrestricted diffusion leads to nonexponential signal decay versus echo number N, but within experimental error the diffusion attenuation is still only a function of g2Dt3EN, where tE is the echo spacing.}, Author = {Hurlimann, M.

Since NMR can be set up to measure the number of nuclei at specific phase angles, the motion of groups of nuclei can be determined very accurately.

With a long train of 90$\,^{\circ}$ pulses, a sustained chain of solid echoes was produced for Na23 in NaF. The peak echo amplitude was found to decay nonexponentially for short times (i.e., the first few echoes), settling down for long times to an exponential decay characterized by a time constant T2?. A theoretical expression for T2? derived in a similar manner to that for a single-ingredient spin system, described previously by Waugh and Wang and by Mansfield and Ware, does not fit the experimental data. A more general theoretical approach to the multiple-pulse experiments is developed, based on the use of a logarithmic operator. Using this formalism together with a line-narrowing model similar to Anderson's theory of spectral line narrowing in solids in the presence of an exchange interaction, a new expression for T2? is derived. Some related long-pulse experiments have been performed in which the Na23 magnetization following an initial 90$\,^{\circ}$ pulse is spin-locked in a low rf field. These experiments simulate the mean rf field in the multiple-pulse experiment. Oscillation of the spin-locked magnetization is observed. Theoretical expressions are derived which describe these oscillations, and their relation to the multiple-pulse experiments is discussed.

The rf phase of the coherent pulses is shifted 90$\,^{\circ}$ with respect to the initial pulse. It is shown that this pulse sequence will produce a sustained "solid-echo" chain for times much greater than T2, i.e., approaching the spin-lattice relaxation time. This therefore shows promise as a new method of chemical-shift measurement in solids, as well as a direct method of measuring the rotating-frame spin-lattice relaxation time T1?. Except for a small initial oscillation, the amplitudes of successive even or odd echo maxima in CaF2 are found to decay exponentially with a time constant T2?. It is shown theoretically that a simple diagonal assumption for the density matrix plus the rotational symmetry properties of the dipolar Hamiltonian to 90$\,^{\circ}$ pulses could explain the observed ?-5 dependence of T2? as well as the oscillatory effect. Numerical evaluation of the magnitude of T2? based on a cumulant-moment approximation gives good agreement with experiment. Further related experiments have been performed by spin-locking the F19 magnetization in long pulses of low amplitude. These experiments are intended to simulate the multiple-pulse sequences by replacing the coherent-pulse train with its mean field. The results reveal considerable oscillatory effects due to mutual exchange of energy between the Zeeman and dipolar subsystems in the rotating reference frame. A theoretical analysis is given which supports these effects. An estimate is made of the Zeeman dipolar cross-relaxation time, and is compared with Provotorov's theory as modified by Walstedt. In the multiple-pulse experiment, the "solid-echo" amplitude modulation may be ascribed to mutual energy exchange between the rf Zeeman energy in the zeroth Fourier harmonic of the pulse train (the mean pulse field) and the dipolar energy. Because of the higher harmonics in the Fourier expansion, however, the initial oscillatory effects disappear as ? increases.}, Author = {Mansfield, P. and Ware, D.}, Date-Added = {2006-09-04 13:14:11 +0200}, Date-Modified = {2006-09-04 13:16:18 +0200}, Doi = {10.1103/PhysRev.168.318}, Journal = {Phys.

The results show that under the given conditions SFG NMR and PFG NMR can provide tracer diffusion coefficients for 7Li diffusion down to about 10-14 and 10-13 m2/s, respectively. SFG and PFG NMR are complementary methods. The paper demonstrates advantages and disadvantages of each method with a concrete example and why it is desirable to be able to apply both methods to the same sample.}, Author = {Marion Fischer, D. and Duwe, Peter and Indris, Sylvio and Heitjans, Paul}, Date-Added = {2006-09-04 11:51:18 +0200}, Date-Modified = {2006-09-04 11:51:35 +0200}, Journal = {Solid State Nuclear Magnetic Resonance}, Keywords = {Diffusion, Lithium, SFG NMR, PFG NMR}, Number = {2}, Pages = {74--83}, Title = {Tracer diffusion measurements in solid lithium: a test case for the comparison between NMR in static and pulsed magnetic field gradients after upgrading a standard solid state NMR spectrometer}, Ty = {JOUR}, Url = {http://www.sciencedirect.com/science/article/B6THK-4C47M0W-2/2/1326b04f87facd2d6e49738bf3b6f2eb}, Volume = {26}, Year = {2004}} @article{Sorland:1997lr, Author = {Sorland, Geir Humborstad}, Date-Added = {2006-09-04 11:48:47 +0200}, Date-Modified = {2006-09-04 11:49:12 +0200}, Journal = {Journal of Magnetic Resonance}, Number = {1}, Pages = {146--148}, Title = {Short-Time PFGSTE Diffusion Measurements}, Ty = {JOUR}, Url = {http://www.sciencedirect.com/science/article/B6WJX-45NJPN6-N/2/fe7f5766085cc329540b5fbbf4f0b7c2}, Volume = {126}, Year = {1997}} @article{stejskal:3597, Author = {E.

The authors show that the time shape of the gradient can be evaluated by using the ratio of free induction decay (FID) to its first derivative coming from a small sample placed inside the RF coil. In computer simulation and experiments, the gradients obtained using this approximation of the actual solution agreed well with the true gradients. The advantages to the method proposed here are: no additional apparatus is required to measure the gradient and the method may be utilised even for very small bore magnets without degrading gradient performance. }, Author = {E Yamamoto and H Kohno}, Date-Added = {2006-08-29 16:20:26 +0200}, Date-Modified = {2006-08-29 20:19:27 +0200}, Journal = {Journal of Physics E: Scientific Instruments}, Keywords = {PFG, shape}, Number = {9}, Pages = {708-711}, Title = {Gradient time-shape measurement by NMR}, Url = {http://stacks.iop.org/0022-3735/19/708}, Volume = {19}, Year = {1986}} @article{stejskal:288, Author = {E.
