We report on the direct measurement of the molecular diffusion coefficients of water confined to purified bovine nuchal ligament elastin by high resolution q‐space NMR imaging. The experimental data indicate that water trapped within an elastin fiber has two distinguishable molecular diffusion coefficients. The component with the slowest mobility has a diffusion coefficient on the order of 10−6 cm2/s that varies inversely with the diffusion time and is seen to reduce near 37°C. The component with higher mobility has a diffusion coefficient reminiscent of free water but is observed to also behave similarly at 37°C. From our experimental data we extract the surface‐to‐volume ratio of pores within elastin and associated changes as a function of temperature. © 2007 Wiley Periodicals, Inc.

This work focuses on analyzing the dynamics of spin I=1 nuclei evolving under a simple two pulse echo cycle and a magic echo cycle by average Hamiltonian theory. The work highlights how spectral artifacts introduced by finite pulse widths can be removed by cycling the phases of the receiver and transmitter in a well defined way. In addition, it is shown that a magic echo cycle can refocus both the quadrupolar interaction together with any offset Hamiltonian. Due to higher convergence in the Magnus expansion magic echo based quadrupolar echo spectroscopy outperforms the conventional two pulse echo sequence.
