Introduction: Research in spectroscopy and theoretical chemistry has been carried out at the department since the early fifties. In its present form the Spectroscopy Group is a joint research and teaching lab established by the Faculty of Chemical Technology and Biotechnology (VBK) of the Budapest University of Technology and Economics (BME) together with the Research Center for Natural Sciences at the Hungarian Academy of Sciences. The research activity of group includes the study of phenomena in photophysics, photochemistry, and photobiology using various optical spectroscopic techniques like steady-state absorption and fluorescence, CD-ORD, and laser flash photolysis. The Spectroscopy Group also has a strong tradition in theoretical chemistry including a wide range of topics from the development and application of high-level quantum chemical methods to theoretical rovibrational spectroscopy.
