The superhyperfine (shf) interactions of D   i 0centres were measured by ENDOR and compared with those of H   i 0centres (H   i 0= H atom on interstitial lattice position). The isotropic shf constants of the nearest K and Cl neighbours are smaller for D   i 0centres than for H   i 0centres: a H (K)/ a D (K) = 1.165 and a H (Cl)/ a D (Cl) = 1.026. In a model calculation it is shown that the large difference in isotope effect of the K and Cl neighbours can be understood as a consequence of the overlaps of their ion cores. At least 30% of a H (K) and 10% of a H (Cl) are only due to zero‐point vibration of the H atom.
