Program allows:
  • Quick and convenient approximation of dielectric spectrum with model functions using Levenberg-Marquardt algorithm.
  • Rough approximation by user and use user-parameters as staring.
  • Visualized retrieved curves, including analysis components in real time.
Friendly interface. In general case dielectric response is complex, where real part represents dielectric permittivity and imaginary dielectric losses. Difficulty in data approximation received from a so call complex experiment lies in simultaneous fitting of real and imaginary part of dielectric response and in approximation parameters. Program ProFit solves this problem successfully. As separated function for approximation of experimental data superposition of Yonshire and Havriliak-Negami is used. Possibility of adding several components of Yonshire and Havriliak-Negami in cases with more than one relaxation process. It should be noticed that considering the fact that Havriliak-Negami is empirical modification of Debye relaxation function, with the help of ProFit approximation of experimental data with possess characterized with simple Debye spectrum is possible.
