the invention relates to an nmr analysis system and method for obtaining an nmr signal from a liquid solution enhanced in relation to the value that it would have on the basis of the thermodynamic equilibrium . it has been discovered in a surprising manner that if the spins of the cores of a highly - polarised polarisation source and the spins of the cores of the liquid solution are irradiated such that a polarisation transfer , such as a hartmann - hahn transfer , of the spins of the cores of the source to the spins of the cores of the liquid solution is carried out by means of a coherent coupling resulting from the dipolar field created by the cores of the source , an nmr signal of the liquid solution is obtained , said signal being significantly enhanced in relation to the value it would have on the basis of the thermodynamic equilibrium .
