Abstract
Nuclear spins of particular atoms (14N) which distinctively exist in a crystal of an active pharmaceutical ingredient is manipulated, so that an initial magnetization (modulated magnetization) is caused in nearby hydrogen atoms which exist near the particular atoms in the crystal. The initial magnetization of the nearby hydrogen atoms is spread to peripheral hydrogen atoms which exist at a periphery of the nearby hydrogen atoms in the crystal. A magnetization which is spread in the crystal is directly or indirectly observed.
