ABSTRACT:
Process for the excitation and acquisition of NMR signals, particularly for the analysis of molecules dispersed in a solvent, such as for example water. A specimen to be analyzed is first subjected to a series of impulses (1) corresponding to a high resolution NMR test to be carried out. Then there is applied to the specimen a first pulsed field gradient (2) in a given direction, and then the specimen is subjected to a 180.degree. selective pulsed radiofrequency field (3) affecting all the spectrum except the resonance frequency of the water or corresponding solvent. Then a second pulsed field gradient (4) identical to the first is applied to the specimen. Then the acquisition and processing of the resulting NMR signals are effected.
