55Mn and 187Re NQR spectral studies of modulation effects of mutual motions of electrons and atomic nuclei in cyclopentadienyl tricarbonyl manganese and rhenium complexes

Abstract

The 55Mn and 187Re NQR spectral parameters for cyclopentadienyl tricarbonyl complexes of these metals at 77 K are presented. An analytical dependence between e 2 Qq zz and η has been shown to exist. Such dependence may be associated with slow mutual electron-nuclear motions in these complexes.
