One- and two-dimensional NMR spectroscopy with a magnetic-resonance force microscope

Abstract

(Graph Presented) At the micrometer scale: Chemical interactions at the atomic level have been characterized with localized spectroscopy by using magnetic-resonance force microscopy to locate slices of 2.0 μm thickness in a heterogeneous sample (see picture). To recover the chemical-shift information, the field gradient was temporarily switched off by removing its source mechanically. This technique allows high-resolution one- and twodimensional NMR spectra to be recorded. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
