The nuclear spin-lattice relaxation time, T_1, and the Knight shift of Sc^<45> disolved dilutely in Pd and Pt are measured in the temperature region of 1.4∼4.2K. T_1's of Sc^<45> in Pd and Pt are about 10 to 20 times larger than that of pure Sc^<45> metal. These data are compared with those of V^<51> reported previously. Ab initio calculations of the relaxation rates of Sc^<45> and V^<51> in Pd are carried out. In the case of Sc^<45> in Pd, the resonance d states lie fairly above the d band and the Fermi level of Pd and the contribution from d electrons to the relaxation rate can be neglected, whereas in pure Sc^<45>, this contribution is large. In the case of V^<51> in Pd, the resonance peaks of d stated in the local density of states at the V^<51> site lie just above the d band and the Fermi level of Pd. The d electrons make comparable contributions to the relaxation rate with s electrons.
