We report on ^{13}C NMR measurements on potassium intercalated C_{60} compounds. By using high resolution NMR technique we were able to char­acterize the different thermodynamically stable phases. The effects of the intercalation on the molecular dynamics as well as on the electronic proper­ties will be discussed. We also performed the magnetic susceptibility mea­surements on Rb_{4}C_{60} compound, which reveal the activation temperature behavior with the activation energy about 1200 K. By comparison with the NMR and ESR data of the same sample we conclude that the additional electrons are localized on the C_{60} molecule and form the spin singlet ground state.
