This has enabled us to implement the first all-electron scalar relativistic calculations of hyperfine coupling tensors at DKH2 level. Furthemore we have presented a general, relativistic two-component DFT approach for the unrestricted calculations of electronic g-tensors, based on DKH Hamiltonian. Additionally we have derived the expressions for the evaluation of hyperfine structurs and two-component unrestricted treatment of g-tensor within the Resolution of Identity Dirac Kohn Sham method developed by Stanoslav Komorovsky and Michal Repisky in collaboration with other members of the group of V. G. Malkin. All these approaches have been extensively validated.}, subject = {Elektronenspinresonanz}, language = {en} } @phdthesis{Remenyi2006, author = {Remenyi, Christian}, title = {Density Functional Studies on EPR Parameters and Spin-Density Distributions of Transition Metal Complexes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-19848}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2006}, abstract = {In dieser Arbeit wurden EPR-Parameter und Spindichteverteilungen von {\"U}bergangsmetallkomplexen mit Hilfe der Dichtefunktionaltheorie (DFT) berechnet.
