Low temperature liquid and solid state NMR, hydrogen transfer and
hydrogen bonding, catalysis, isotope effects and labels, crystalline and
amorphous solids, surfaces.
The
research program of Prof. Limbach was focused on the design and the study by
NMR spectroscopy of the structure and dynamics of isotopically
labeled molecular model systems for proton and
hydride transfer.
The range
between small organic molecules embedded in liquids, solids and surfaces,
modified enzymes, oligonucleotides and transition
metal hydrides as well as transition metal nanoparticles was covered. For that purpoes, variable temperature liquid and solid state NMR
spectroscopy were applied.
The aim
was to measure kinetic, equilibrium and geometric isotope, tunneling,
solvent and surface effects of hydrogen transfer in high- and low-barrier hydrogen
bonds and in the coordination sphere of transition metal catalysts, and to
model the results theoretically.
Some of
this research is currently continued in the groups of Prof. Dr. Gerd Buntkowsky, Technical University of Darmstadt, Prof.
Dr. Klaus Weisz, University of Greifswald, Dr. habil.
Ilya Shenderovich, University of Regensburg and Dr. Peter Tolstoy, St.
Petersburg State University
