Computer-Assisted Analysis of the EPR Spectrum of Cu2+ :ZnF2
The EPR spectrum of a Cu2+ -doped single crystal of zinc fluoride has been measured at X band. This was done by utilizing a laboratory automation system for the IBM 1800 by which we are able to control the experimental observations and obtain improved results. Other computer programs were applied to analyze the spectra for the magnetic parameters, i.e., the g values, the copper hyperfine structure constants, and the fluorine superhyperfine structure constants. Covalency measures were then derived from these values. The details of the spectrum and its analysis, the laboratory automation system, and the covalency parameters compared with other copper compounds will be discussed.
