| titleOfInvention | Nuclear magnetic resonance measuring method for solid samples |
| abstract | In a nuclear magnetic resonance measuring method for solid samples, there are provided the steps of exciting a nuclear spin of a solid sample placed in a static magnetic field by allowing exciting pulses to pass through a receiver coil. A FID signal (Free Induction Decay signal) is received from the excited nuclear spin by applying reading pulses after a lapse of time τ after applying the exciting pulses is finished. An Inversion Recovery IR - Nuclear Magnetic Resonance NMR spectrum is obtained by subjecting the FID signal to a frequency conversion process. The estimation of a constituent ratio of constituent substances of the solid sample is achieved by acquiring a plurality of FID signals while changing the period of time τ, by calculating IR-NMR spectra based on these FID signals, by obtaining a longitudinal relaxation curve by plotting spectrum strength with respect to time τ in a specific frequency of the TR-NMR spectrum, and by making a regression analysis while regarding the longitudinal relaxation curve as a total sum of a plurality of longitudinal relaxation curves differing in longitudinal relaxation time. |
