Kaim's interdisciplinary research covers the areas of radical stabilization by
metal coordination ('
non-innocent ligands'), coenzyme models, the extension of
mixed-valence chemistry, electron transfer effects on M-C and M-H bonds, the crystallization of new organic radicals and the electron transfer properties of boron compounds, as well as spectroelectrochemistry in the IR, UV/VIS/near-infrared regions as spectroscopic probes for electron transfer sites and the consequences of
electron transfer or
charge transfer on structure and bonding,
EPR spectroscopy as a less common but highly useful methodology and
CV (cyclic voltammetry). He is the co-author of more than 700 publications in peer-reviewed journals. ==Publications==
