DYNAMICS IN HYDROGEN BONDS -PERSPECTIVES OF INFRARED AND FAR-INFRARED SPECTROSCOPY

Author Institution: Physical Chemistry II, Ruhr-University Bochum,; 44780 Bochum, GermanyThe focus of our investigations lies in a detailed microscopic understanding of intermolecular interactions. Within the last year we have developed new radiation sources in the IR (high power continuous wave OPO) and THz frequency region (p-Ge laser). Using (high resolution) laser spectroscopy we were able to answer the following fundamental questions in chemistry and biophysical chemistry: \\ How fast tunnel the protons in H-Bonds? \\ How stiff are the hydrogen bonds in and around sugars ? \\ What do we learn from the low frequency modes of solvated proteins
