ABSTRACT:
The invention relates to a method and a device for examining molecules by means of NMR spectroscopy. It is the object of the invention to be able to characterize a sample with a high resolution and comprehensively. The object is solved by a method and an associated device for examining a sample by means of nuclear magnetic spectroscopy by measuring heteronuclear and homonuclear J-couplings in a small magnetic field and by using the measured heteronuclear and homonuclear J-couplings for characterizing the sample.
