Title: Transverse Spin Relaxation in Liquid X

Abstract

Using spin-echo NMR techniques we study the transverse spin relaxation of hyperpolarized liquid X{sup 129}e in a spherical cell. We observe an instability of the transverse magnetization due to dipolar fields produced by liquid X{sup 129}e , and find that imperfections in the {pi} pulses of the spin-echo sequence suppress this instability. A simple perturbative model of this effect is in good agreement with the data. We obtain a transverse spin relaxation time of 1300sec in liquid X{sup 129}e , and discuss applications of hyperpolarized liquid X{sup 129}e as a sensitive magnetic gradiometer and for a permanent electric dipole moment search.

  • We propose a fast and accurate determination method for transverse relaxation of the spin-exchange-relaxation-free (SERF) magnetometer. This method is based on the measurement of magnetic resonance linewidth via a chirped magnetic field excitation and the amplitude spectrum analysis. Compared with the frequency sweeping via separate sinusoidal excitation, our method can realize linewidth determination within only few seconds and meanwhile obtain good frequency resolution. Therefore, it can avoid the drift error in long term measurement and improve the accuracy of the determination. As the magnetic resonance frequency of the SERF magnetometer is very low, we include the effect of the negativemore » resonance frequency caused by the chirp and achieve the coefficient of determination of the fitting results better than 0.998 with 95% confidence bounds to the theoretical equation. The experimental results are in good agreement with our theoretical analysis.« less
  • Muon spin relaxation has been used to study transverse spin freezing in a-Fe{sub x}Zr{sub 100{minus}x} and a-Fe{sub 90{minus}x}Ru{sub x}Zr{sub 10}. The derived phase diagrams, while generally consistent with model calculations, exhibit some significant differences. Comparison between zero-field and applied field measurements shows that T{sub xy} is strongly affected by a field and falls as B{sup {minus}1}, contrary to mean field predictions. {copyright} 2001 American Institute of Physics.
  • Experimental proof is presented that some of the motions responsible for transverse relation (T/sub 2/) in deuterium magnetic resonance (/sup 2/H NMR) experiments on acyl chains of a model membrane in the liquid-crystalline phase are extremely slow on the /sup 2/H NMR time scale being characterized by a correlation time tau/sub 2/ >> 10/sup -5/ s. The experiments used to investigate these slow motions involve a form of the Carr-Purcell-Meiboom-Gill pulse sequence modified so as to be suitable for /sup 2/H NMR. The most plausible mechanism responsible for T/sub 2/ relaxation is the gradual change in the average molecular orientationmore » due to lateral diffusion of the phospholipid molecules along curved membrane surfaces. A procedure for separating contributions to T/sub 2/ relaxation due to slow and fast motions is described.« less
  • We investigate the dynamics of the one-dimensional S = (1/2) isotropic XY model and transverse Ising model in the high-temperature limit by using the method of recurrence relations. We obtain the relaxation functions as well as some Brownian analogs of the generalized Langevin equation for a tagged spin S/sub j//sup x/ in these models, namely, the memory functions and the random forces. We find that the realized dynamical Hilbert spaces of the two models have the same structure, which leads to similar dynamical behavior apart from a time scale.
  • The low-frequency line in the ZF NMR spectrum of PFO3S is much broader than the high-frequency line while for the T P NMR spectrum the high-frequency line is broader than the low-frequency line. The experimental conditions needed for the occurrence of such differential line broadening (DLB) in coupled spin systems are discussed. Experimental measurements of T/sub 1p/ and the line widths for fluorine-19 and phosphorus-31 are reported for the PFO3S ion in water-ethylene glycol solutions. These results are compared to the theoretical predictions of Shimizu. Theory and experiment are in excellent agreement. The absolute sign of the spin coupling constantmore » is negative, J/sub PF/ = -870.0 +/- 0.5 Hz. It is shown that T/sub 1p/ measurements of simple two-spin systems can be used to obtain accurate information about the chemical shift anisotropy of the two spins, the bond distance, and the molecular correlation time.« less
