CCSD/6-31G*, UMP2/6-311 ++4G** and UMP2/6-31G* calculations have been carried out on model N-acylaminoxyls. The results have been used to establish the angular dependence of the αβH electron paramagnetic resonance (EPR) hyperfine coupling constants of these free radicals, as well as to assign values to the corresponding MM2 parameters by fitting the molecular conformational hypersurface to the ab initio hypersurface with the help of specially developed computer software. The new parameters have been used for Monte Carlo and molecular dynamics modelling of neoglycolipids.
