We consider the state determination problem using Mutually Unbiased Bases(MUBs). Analogous to Pauli operators of spin-1/2 system, which are experimentally implementable and correspond to the optimum measurement in characterizing the density matrix, for spin-1 and spin-3/2 systems we describe a procedure to construct an orthonormal set of operators from MUBs that are maximally commuting, can be physically realized, and correspond to physical observables. The method of construction is general enough to allow for extensions to higher-dimensional spin systems and arbitrary density matrices in finite dimensions for which MUBs are known to exist.
