    • The invention relates to an NMR analysis system and method for obtaining an NMR signal from a liquid solution (1) 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 (9) of a polarisation source (3) and the spins of the cores (7) of the liquid solution (1) are irradiated such that a polarisation transfer, such as a Hartmann-Hahn transfer, of the spins of the cores (9) of the source (3) to the spins of the cores (7) of the liquid solution (1) 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.
    • 本发明涉及一种从液体溶液(1)获得NMR信号的NMR分析系统和方法,该液体溶液相对于基于热力学平衡的值而增强。 已经以令人惊讶的方式发现,如果照射极化源(​​3)的芯(9)的自旋和液体溶液(1)的芯(7)的自旋以使得极化转移 作为Hartmann-Hahn转移,源(3)的芯(9)的旋转到液体溶液(1)的芯(7)的自旋的转移通过由 由源的核心产生的偶极场,获得液体溶液的NMR信号,所述信号相对于基于热力学平衡的值将显着增强。
