128. ATLAS: Synthesis and Plotting of Hyperfine Patterns of
Electron Spin Resonance Spectra
by Horatio A. Farach and Charles P. Poole, Jr., Department of Physics, University of South Carolina, Columbia, South Carolina 29208 This program plots absorption and first-derivative electron spin resonance spectra containing between two and ten hyperfine components of arbitrary amplitude. The program is restricted to spectra with equally spaced lines of constant width. The input data consist of the hyperfine coupling constant (interval in gauss between lines), the total linewidth, the relative intensity of each line, the total scan in gauss, and the center of the spectrum scan in gauss. In addition, one must select the lineshape (Lorentzian or Gaussian) and type of display (absorption or first derivative). When the first derivative plot is obtained, the total observed peak-to-peak linewidth is also given. In addition, it is possible to obtain this linewidth without a graph. NOTE: Explicit input instructions for using this program are contained in the COMMENT cards at the beginning of the program. FORTRAN IV (IBM 7040) Lines of Code: 276 Recommended Citation: H. A.
