Multi-frequency CW-EPR Simulations

For research level quality yet ease of handling, XSophe provides the means for the simulation and analysis of CW and Pulse EPR spectra.. With a variety of simulation strategies, XSophe is poised to handle the complex systems present in modern research environments. This highly-developed simulation suite features an easy to use interface to assist in defining the spin system, interactions, and experimental parameters for spectrum simulation.

The XSophe simulation suite is intended to provide an easy-to-use yet powerful simulation environment for CW-EPR.  The graphical environment allows rapid definition of the spin system, the spin Hamiltonian, instrumental parameters, and optimization parameters.  Simulation visualization is based on Xepr which provides a feature rich environment for data processing, manipulation, and comparison.

The versatile simulations available include conventional experiments and special 2D experiments:

  • Continuous Wave – EPR spectra
  • Orientation Dependent CW-EPR spectra
  • Energy Level Diagrams
  • Transition Surfaces
  • Field vs.
    • Goniometer angle
    • Temperature
    • Microwave Frequency

Spectra are simulated based on full Matrix Diagonalization with the Sophe partitioning scheme.  Further, the superhyperfine interactions may be treated with 1st or 3rd order perturbation theory.  This methodology imposes no limitations on the spin systems to be simulated:

  • Isolated Systems
  • Magnetically Coupled Systems
  • Unlimited Electron Spins
  • Unlimited Nuclear Spins
  • Multiple Nuclear Isotopes
      Optimization Control

      Similarly, XSophe imposes no limitations on the CW-EPR spectrum to be simulated:

      • Solution Spectra
      • Powder Spectra
      • Single Crystal Spectra
      • Symmetry
      • Isotropic
      • Axial
      • Orthorhombic
      • Monoclinic
      • Triclinic

      The ultimate in data analysis is achievable through direct optimization routines for the simulation of experimental spectra:

      • Hooke and Jeeves
      • Simplex
      • Simulated Annealing
      • Raw Data Comparison
      • FFT Spectral Comparison
