Abstract:
1. An NMR measurement method for obtaining NMR spectra, respectively, of plural components of a sample when the nuclear spins in the components have a uniform longitudinal magnetization relaxation time in each individual domain of the sample due to spin diffusion, said method comprising the steps of: irradiating a pulse sequence to the sample in order to measure the above-described uniform longitudinal magnetization relaxation time of nuclei; after a lapse of a given period of time t, acquiring a high-resolution NMR spectrum by nullifying the spin diffusion of the nuclei having the uniform longitudinal magnetization relaxation time; repeating the irradiating step and the NMR spectrum-acquiring step while varying the period of time t to obtain plural high-resolution NMR spectra; and classifying the high-resolution NMR spectra according to value of longitudinal magnetization relaxation time by inverse Laplace transform, based on differences in recovery rate of NMR signal intensity that recovers dependently on longitudinal magnetization relaxation time.
