Abstract

The programMossAprovides a straightforward approach to the fitting of57Fe conventional and synchrotron energy-domain Mössbauer spectra. Sites can be defined simply by mouse clicks and hyperfine parameters can be constrained to constant values, within specific ranges, and can be coupled linearly between different subspectra. The program includes a full transmission integral fit with Lorentzian line shape (conventional source) or Lorentzian-squared line shape (synchrotron source). The fitting process is graphically displayed in real time while fitting and can be interrupted at any time. Gaussian-shaped quadrupole splitting distributions for analyzing nonmagnetic amorphous materials are included.MossAis designed especially for the rapid and comprehensive analysis of complex Mössbauer spectra, made possible by its native graphical user input.
