Magnetic Interactions in Molecules and Solids, C. de Graaf and R. Broer (textbook, Springer, 2015) 100 papers in scientific journals, including several books chapters
Development and application of methods for studying spectroscopic and magnetic properties of materials in the solid state using ab initio molecular quantum chemical methods, using embedded cluster models. The local approach has a basis in early work on symmetry breaking.
Non-orthogonal configuration interaction for the treatment of local excitations in compounds with strong electron correlation effects.
Isotropic and anisotropic magnetic interactions in molecules and solids; switching processes in bi-stable transition metal compounds. With Coen de Graaf and others.
Interpretation and prediction of core excitation spectra in transition metal compounds; combined treatment of electron correlation and relativistic effects. With Paul Bagus.
Design of donor-acceptor blends for organic photovoltaic materials; enhanced exciton separation; study of the mechanism of singlet fission. With Remco Havenith.
