  • Abstract
    Flux density measurements at the highest accuracy obtained via nuclear magnetic resonance differ from the average flux density over the sample. Spatial variations of the flux density cause line-shape asymmetries which shift the measured frequency by a measurement-method-dependent amount. A method has been devised for correcting for this effect experimentally
