PURPOSE:To provide the peak of a spectrum in a pure absorption waveform and dispersion waveform, by using complex set data obtained from a freely induced attenuation signal by a 2-D nuclear magnetic resonance measurement to prepare a specified spectrum data. CONSTITUTION:A 2-D nuclear magnetic resonance measuring device is so ar ranged that a resonance signal to be induced in a sample coil 2 arranged in an electrostatic field of a magnet 1 is passed through two channels of detection systems CHa and CHb different by 90 deg. in the phase to obtain a freely induced attenuation signal. Then, the development period after the irradiation of a preparatory pulse is set at t1 while the detection period after the irradiation of the detection pulse is at t2 to form two complex set data S1 and S2 compris ing a plurality of freely induced attenuation signals. Then, data obtained by a double complex Fourier transform of the data and an inversion data thereof are used to prepare a specified spectrum data. Thus, diagonal and crossing peak of a spectrum can be displayed in a pure absorption waveform and disper sion waveform thereby facilitating the analysis. |
