Outline of Final Research Achievements

Though specific bond scission of molecules is known to occur by soft X-ray irradiation, which bond being cut is fixed by molecules. On the other hand, the molecules excited by ultraviolet changes its reactivity. Ever unknown enhancement of specific bond scission by soft X-ray irradiation of excited triplet molecules (long life-time to emit phosphorescence) formed by ultraviolet irradiation. In addition, deeper insight about the mechanism of the selective bond scission by the soft X-radiation was deepened.
