Abstract:
1. A method for analyzing a sample utilizing nuclear magnetic resonance under terahertz-wave irradiation, comprising: a first step of irradiating the sample with terahertz waves and measuring the terahertz-wave absorption spectrum or the terahertz-wave reflectance spectrum of the sample; a second step of placing the sample in a static magnetic field and measuring the nuclear magnetic resonance signal and the relaxation time of the nuclear magnetic resonance signal of the sample; a third step of placing the sample in the static magnetic field and measuring the nuclear magnetic resonance signal and the relaxation time of the nuclear magnetic resonance signal of the sample under terahertz-wave irradiation; and a fourth step of obtaining information about the relationship between the spectrum measured in the first step and information about the sample on the basis of the nuclear magnetic resonance signal and the relaxation time of the nuclear magnetic resonance signal measured in each of the second step and the third step.
