Recent advances in solid-state nuclear magnetic resonance spectroscopy of exotic nuclei

摘要

We present a review of recent advances in solid-state nuclear magnetic resonance (SSNMR) studies of exotic nuclei. Exotic nuclei may be spin -1/2 or quadrupolar, and typically have low gyromagnetic ratios, low natural abundances, large quadrupole moments (when I 1/2), or some combination of these properties, generally resulting in low receptivities and/or prohibitively broad line widths. Some nuclides are little studied for other reasons, also rendering them somewhat exotic. We first discuss some of the recent progress in pulse sequences and hardware development which continues to enable researchers to study new kinds of materials as well as previously unfeasible nuclei. This is followed by a survey of applications to a wide range of exotic nuclei (including e.g., Be-9, Mg-25, S-33, K-39, Ca-43, Ti-47/49, Cr-53, Co-59, Ni-61, Zn-67, Ge-73, As-75, Sr-87, In-115, Sn-119, Sb-121/123, Ba-135/137, Re-185/187, Bi-209) most of them quadrupolar. The scope of the review is the past ten years, i.e., 2007-2017. (C) 2018 Elsevier B.V. All rights reserved.
