Abstract
A method of heteronuclear decoupling in magnetic resonance spectroscopy and a device for determining a spectrum where spectra of a first type of nucleus which is spin-coupled to a second type of nucleus are decoupled inter alia in order to obtain a higher resolution. In inter alia phosphorous spectroscopy, during signal acquisition of resonance signals of the first type of nucleus, decoupling pulses are applied to the second type of nucleus, which decoupling pulses have been modulated in amplitude as well as in frequency or phase. The decoupling pulses need hardly be optimized. Very good decoupling is achieved, notably when use is made of surface coils for the transmitter and receiver coils exhibiting a substantial field inhomogeneity. When surface coils are used, suitable decoupling is achieved across a comparatively large volume.
