In all double resonance experiments there are changes in the intensities of observed resonances, whatever the irradiation power levels. The Nuclear Overhauser Effect (NOE) relates to the ratio of the total integrated intensity achieved in the double resonance experiment to that achieved in the single resonance experiment. The double resonance experiment involves presamration of the X nucleus, i.e. irradiation of the X nucleus frequencies before the FID of the A nucleus is sampled. The name Nuclear Overhauser Effect is applied both to the magnitude of the effect and to the phenomenon itself. Its magnitude depends on the balance of relaxation mechanisms, and its maximum value for an A X experiment in which the X nucleus is saturated, occurring when dipole-dipole mechanisms predominate, is given by... [Pg.125]
