Outline of Final Research Achievements

Three major investigations were accomplished by this research project. The first, the magnetic properties of the radical cation of cycloparaphenylene (CPP) were obtained by an electron spin resonance (ESR) and an electron nuclear double resonance (ENDOR) measurements. Secondarily the parallel measurement of X-ray diffraction and ESR spectroscopy was done for the host-gust system of radical molecule PTIO in TPP metal- organic framework crystal. Finally the ground state of electron spin triplet was confirmed for O2@openC60 molecule by using multi-frequncy ESR measurements.
