Date Oct. 24, 1985.Increased spatial sensitivity (FIGS. 4) or spatial tolerance (FIGS. 1) in selectively manipulated NMR sample analysis is excited from a spatially inhomogeneous FR field using pulse sequences which operate to exclude all spins deviating from a selected initial orientation (FIGS. 4 and 5) or to inclusively extend the applicable flip angles over a range of initial spin orientation (FIGS. 1).
