Abstract
A new method of spatial localization in solids using the high off-resonance sensitivity of heteronuclear polarization transfer is presented in theory and experiment. Application in imaging and volume-selective spectroscopy are discussed and test experiments to this end are reported.
Claims5
A method for volume-selective nuclear magnetic resonance (NMR) spectroscopy or NMR-imaging comprising the steps of,
- a) locating a sample within a homogeneous static magnetic field B.sub.0, said sample containing a first and second nuclear species,
- b) applying a magnetic field gradient to the sample and,
- c) irradiating a contact-RF-Pulse into the sample within a time interval during which the magnetic field gradient is applied, whereby a spin order transfer (SOT) from the first to the second nuclear species located in a slice transverse to a gradient direction of the magnetic field gradient is effected.
