Quadrupole Nutation NMR in Solids
View through CrossRef
Abstract
The nutation frequency of a quadrupolar spin I depends on the quadrupole interaction. From nutation spectra, therefore, one obtains information about the direct surrounding of the atom. The theory of the straightforward and of more complicated nutation NMR experiments is outlined. Two applications of nutation NMR, to 23Na in zeolites and 27Al in alumina, are shown. In this way in CaO • 6 Al2O3 penta-coordinated aluminum has been detected
