The basis for our research projects within the area of theoretical chemistry is the TURBOMOLE quantum chemical program package, initially developed in the group of Reinhart Ahlrichs at the University of Karlsruhe and at the Forschungszentrum Karlsruhe. With almost 20 years of continuous development TURBOMOLE has become a valuable tool used by academic and industrial researchers. It is used in research areas ranging form homogeneous and heterogeneous catalysis, inorganic and organic chemistry to various types of spectroscopy, and biochemistry. After the retirement of Reinhart Ahlrichs the responsibility for the development of TURBOMOLE has been taken over by a company founded by the main developers of the program.
