Abstract
The nuclear spin hyperpolarization method includes the steps of: irradiating a sample, prepared by doping solid benzoic acid derivative with a pentacene derivative, placed in a space where a static magnetic field is formed by a main magnetic field forming unit, with a laser beam from a laser source; following the light irradiation, irradiating the sample with a microwave from a microwave source while applying a sweeping magnetic field; and after repeating the application of sweeping magnetic field, light irradiation and microwave irradiation, dissolving the benzoic acid derivative in the sample. This enables generation of an aqueous solution containing benzoic acid derivative of which nuclear spins are hyperpolarized.
