| Outline of Final Research Achievements |
Changes in temperature of a solid material containing metal ions may cause electron jump between (1) atomic orbitals in the metal ion or (2) the metal ion and carbon atoms or (3) metal ions arranged in the crystal, which in turn causes a drastic change in the magnetic property of the solid.
This research has showed that the electron jump can be detected using the accompanying alterations in molecular shape and in ionic size with a commercially available apparatus called NMR spectrometer.
With this method, we have succeeded in measuring the frequency of an electron jump, which is difficult to measure by other experimental methods.
