Abstract
A method for non-destructive chemical and tomographic structural analysis of an object by nuclear magnetic resonance wherein a nonmagnetic object which is substantially transparent to electromagnetic radiation at the nuclear magnetic resonance frequency is subjected to periodic motion while transverse magnetization is generated, subjected to at least one magnetic field gradient pulse of sufficiently short duration that the object does not move appreciably while the pulse is on, and a resulting free induction decay signal is detected, collected in a computer and processed by Fourier transformation to obtain the chemical shift spectrum at various positions within the object.
