Abstract

The QI frequencyv Q for99Ru in CeRu2 and ThRu2 differed very much from that for other RRu2 compounds with 3+ rare earth, while such a difference was not observed for a111Cd probe. The Ru charge calculated to fit the data for the99Ru probe is 1.59 while in the case of111Cd data, it is 1.63. It is shown that the apparent insensitivity of111Cd to the 3+ and 4+ valence is due to the corresponding lattice contributions being almost equal in magnitude though opposite in sign.
