\chem{Cs_{1}C_{60}} . The \isotope{13}{C} NMR spectrum allows, when the Magic Angle Spinning (MAS) technique is used, to get information about the electronic structure of this phase, which points out that the spin density is not uniformly distributed on the \chem{C_{60}} ball. An estimation of the strength of the quadrupolar effects on \isotope{133}{Cs} is then given, which shows that it is possible to analyse the \isotope{133}{Cs} spin-lattice relaxation time T_{1} in terms of magnetic effects. A comparison with the T_{1} of \isotope{13}{C} is then justified and allows us to point out the importance of low dimensional antiferromagnetic fluctuations in this compound. We also investigate the nature of the magnetic ground state in \chem{Cs_{1}C_{60}} : the broadening of the spectra states unambiguously its magnetic nature and a detailed analysis of their shape gives further indications on the antiferromagnetic nature of the magnetic order, which seems characterized by a large amount of disorder.
