Professor Edward Solomon’s research spans the fields of physical-inorganic, bioinorganic, and theoretical-inorganic chemistry. His work focuses on spectroscopic elucidation of the electronic structure of transition metal complexes and its contribution to reactivity. He has developed new spectroscopic and electronic structure methods and applied these to active sites in catalysis. He has made significant contributions to our understanding of metal sites involved in electron and oxo transfer, copper sites involved in O2 binding, activation and reduction to water, in structure/function correlations over non-heme iron enzymes, and in the correlation of biological to heterogeneous catalysis.
