Electron Paramagnetic Resonance of Dipyridylhyphen;Coordinated Ag2plus;(4d9)

摘要

The paramagnetic resonance spectrum of solid Ag dipy2 S2O8and its solution in nitric acid have been observed at 77deg;K. The frozen solution exhibits silver hyperfine and nitrogen superhyperfine structure. Due to a strong axialganisotropy it is possible to determine the principal values of the hyperfine interaction tensors. With these values it is found that the hole in the silverdshell is highly delocalized. Wavefunctions for the unpaired electron are calculated on the basis of the experimental results. Exchange narrowing in the solid wipes out the hyperfine structure.
