Abstract
For improving the spectral resolution and/or the signal-to-noise ratio of a nuclear magnetic resonance apparatus for examining first types of atomic nuclei that are nuclear-magnetically coupled to second types of atomic nuclei, signals are additionally emitted on the resonant frequency of the second type of atomic nucleus during the examination of the first type of atomic nucleus. To this end, the nuclear magnetic resonance apparatus includes a reception channel and only one transmission channel for both resonant frequencies. The transmission channel contains a respective synthesizer for each resonant frequency, which define the transmission frequency and contains a modulator unit shared in common by both resonant frequencies.
