Abstract

PURPOSE:To make it possible to obtain the information on the coupling conditions between specified nuclei by successively varying the irradiation period of the pulse group applied to a sample in advance of an observational high-frequency pulse or the irradiation interval therebetween. CONSTITUTION:With an attenuator 3 turned off and a gate circuit 2 opened, an observational high-frequency pulse P1 is supplied to a nuclear magnetic resonance probe 4 from a generator 1 and applied to a sample in the probe. According to the obtained signals, a Fourier transform is performed by a processing circuit 6 and a computer 7. Then, according to the obtained nuclear magnetic resonance spectral, the spectral peak A of the specified nucleus which seems to have a coupling relationship to another nucleus is determined, a high-frequency pulse P2 having a frequency component corresponding to said peak A is applied to the sample in advance of the observational high-frequency pulse, and the measurement is repeated with the irradiation period varied. Thereby, it is possible to know the relaxation time of the nucleus depending on the specified nucleus spectral peak A and the size of the interaction between the nuclei. Moreover, the distance therebetween and the kinetic velocity of a molecule can be made known.
