✦ Synopsis

F hyperfine splitting due to a solitary fluorine atom has been observed in complexes of amines with CuF2 and Cu(BF4)2. Vibronic coupling is postulated to explain this hyperfine splitting. We have investigated the effect of a series of anions, i.e. F-, BF4-, Cl-, Br-and NO3-, on the EPR spectra of cupric amine complexes. These complexes are assumed to have a square planar arrangement of four nitrogen atoms around the central copper atom. The grounds for this assumption are: (1) This is the crystallographically determined structure of cupric amines [l]. (2) Gersmann and Swalen have observed 14N hfs corresponding to four equivalent nitrogen atoms in cupric amine complexes [2]. (3) We have observed seven more or less equally spaced hyperfine lines in our spectra of these complexes in the glassy state. The intensity ratios are consistent with the assumption of four equivalent 14N nuclei, i.e.
