Günter Georg Hoffmann received his Diploma in Chemistry and Biochemistry 1978 in the group of Prof. Dr. Dr.h.c.(H) Günther Snatzke (University of the Ruhr, Bochum, Germany). 1983 he was promoted to Dr. rer. nat. in the same group, working on organic synthesis and Circular Dichroism (CD). At the end of 1983 he joined the group of Prof. Dr. Bernhard Schrader (UGE Essen, Germany) as Postdoctoral Fellow, modifying a commercial FTIR spectrometer for the measurement of Vibrational Circular Dichroism (VCD). Another Postdoc position brought him in the years 1985−1986 to the Max Planck Institute for Radiation Chemistry (Mülheim, Germany), where in the group of Prof. Dr. Alfred R. Holtzwarth and Prof. Dr. Kurt Schaffner he studied Circularly Polarized Luminescence (CPL). 1986 he re-joined the group of Prof. Dr. Bernhard Schrader as Assistant Professor, investigating Vibrational Circular Dichroism (VCD) and several new applications of Raman Spectroscopy. 1989 he won the Bennigsen-Foerder award of the Minister of Science and Education of Northrhine-Westfalia (Germany). Since 2002 he worked with Prof. Dr. Heinz W. Siesler (University of Duisburg-Essen, Germany) on infrared and near-infrared rheo-optical investigations on the structure of polymers and the Raman-spectroscopic determination of temperature in rapidly moving laser spots. 2004 he was appointed Visiting Professor in the group of Prof. Dr. Gijsbertus de With (Eindhoven University of Technology, The Netherlands), working on electrically conducting composites, Atomic force microscopy (AFM), Tip-Enhanced Raman Spectroscopy (TERS) and Tip-Enhanced Raman Mapping (TERM). He is the owner and CEO of Hoffmann Datentechnik HHD.
