The proton magnetic resonance rigid-lattice second moment in YH/sub 1.92/ and YH/sub 1.98/ has been measured in the temperature range 160--200 K. From these the occupancy factors for hydrogen in the octahedral and tetrahedral interstitial sites of the fcc metal lattice have been determined. A significant fraction (approx. = 10--15 %) of the octahedral sites are found to be occupied, consistent with features observed in the optical properties of YH/sub 2/.
