The spin lattice-relaxation rates of short-lived unstable nuclei 25Al and 28P in Pt has been measured by means of the β-NMR technique, in order to study the electronic structure of dilute impurities in Pt. From the obtained spin-lattice relaxation rates, Knight shifts Kc were estimated to be Kc [Al in Pt] = (0.45 ± 0.09) × 10- 3 and Kc [P in Pt] = (4- 4+ 2) × 10- 3 using the Korringa relation. These values were evaluated by comparing to the first principle calculations.
