Abstract
A magnetic resonance signal is acquired from a J -coupled H within an object. After application of a wideband first radio-frequency magnetic pulse, a first frequency-selective radiation pulse is applied to a specific nucleus H coupled to a desired nucleus H through a homonuclear spin-spin coupling (J -coupling), thus multiple-quantum coherences between the nuclei H being generated. A second radio-frequency magnetic pulse is then applied. A second frequency-selective radiation pulse is then applied to the specific nucleus H to generate a single-quantum coherence of the desired nucleus H. Thus, a magnetic resonance signal can be acquired from the desired nucleus H. The acquisition of the signal is robust, adjustment in the phases of the radio-frequency magnetic pulses is not required, and an acquired spectrum is avoided from being visually complicated.
