The hybrid DF/HF calculations for the NS, NO, NN and ONS bridged radicals

Autor: M. Kaftory, A. Zakrassov

Publikováno v: Crystal Engineering. 6:31-42

The hybrid density functional/Hartree-Fock methods (DF/HF) UB3LYP and UB1LYP with 6–31 G(d) basis set have been applied to the atomic spin densities and isotropic hyperfine coupling constants (hfcc’s) calculations of the NS, ONS, NN and NO bridge

Predictions of nitrogen isotropic hyperfine coupling constants in the nitroxide radicals with the aid of DF/HF calculations

Autor: M Kaftory, A Zakrassov

Publikováno v: Journal of Solid State Chemistry. 169:75-80

Nitrogen isotropic hyperfine coupling constants in different nitroxide radicals calculated via ab initio hybrid density functional/Hartree–Fock methods (UB3LYP and UB1LYP) with 6-31G(d) basis set of Gaussian 98 were found to be in a good agreement
