DownloadODFR is intended for simulation of slow-motional EPR spectra for spin-probes (especially nitroxide radicals) in partially oriented samples. The main purpose of the program is the simulation of EPR spectrum angular dependences. Both single- and multiprocessor versions are available.
The detailed description of all models and approximations used in the program is contained in the following reference:

ODFR was created in 2018 in Moscow State University by Prof. Andrey Kh. Vorobiev, mailto: a.kh.vorobiev[[at]]gmail.com
Features
- The program ODFR4 explicitly uses an orientation distribution of the local axial director in the sample frame. This distribution is described by expansion in a series of elements of Wigner D-matrix.
- High-frequency molecular reorientations described by quasi-libration model are incorporated.
- Additional angular-dependent hyperfine splitting can be considered. The quantum numbers for the additional nuclei are not included in the basis set for SLE simulation (e.g., super-hfs on protons or 13C-satellites)
