The first direct detection of99Ru and101Ru NMR: Ru relaxation and the Rundash;17O coupling constant in RuO4. Comparision with OsO4thinsp;

摘要

High resolution NMR spectra of99Ru and101Ru have been observed in CCl4solution of RuO4for the first time. The different NMR parameters (frequencies, linewidths, andT1) have been measured for both isotopes. The17O spectra leads to1J17Ondash;99Ru= 23.4 Hz. The dynamical behavior of RuO4and OsO4is compared using the measurement ofT1andT2on17O,99Ru,101Ru, and189Os.
