Abstract
In a method of operating a nuclear magnetic resonance (NMR) spectrometer in relation to a sample comprising two types of nuclei, a sequence of radiofrequency pulses and delay periods is applied using two different radiofrequency coils, one for each type of nucleus, each coil providing an inhomogeneous radiofrequency field, so that the two coils generate separate but overlapping sensitive volumes for each of the two types of nuclear species, whereby signal intensity is substantially limited to the overlap volume.
