FURTHER CALCULATIONS ON THE NUCLEAR RESONANCE SPECTRUM OF Al27 IN SPODUMENE

Abstract

Calculations of the expected dependence of the relative intensities of nuclear quadrupole resonance lines of Al27 on the orientation of a single crystal of spodumene with respect to a linearly polarized resonant magnetic field H1 show that a suitably oriented single crystal should give rise to lines which are approximately twice as strong as those in a randomly oriented polycrystalline sample. The dependence of the matrix elements, which determine expected nuclear magnetic resonance line intensities, on the strength of a uniform external magnetic field H0 is also given for one particular crystal orientation with respect to both H0 and a linearly polarized field H1.
