Using zero field (ZF) and longitudinal field (LF) μSR we study the magnetic properties of high spin molecules (HSM) with spin S = ¹⁵/₂ and²⁷/₂. The LF-μSR at very low temperatures suggests that in both our samples dynamical field fluctuations are responsible for the muon relaxation. The relaxation rate λ increases as the temperature decreases and then saturates below T<T_c indicating that the dynamics is of quantum nature. The fluctuation rate at T→0 of the different samples is compared.
