This is a research group in structural chemistry led by Dr. Yury V. Vishnevsky at Bielefeld University.
We develop experimental and theoretical sides of gas electron diffraction and methods for molecular structure refinement. This includes such aspects as instrumental work in the laboratory, data measurement and processing, scientific software development, quantum-chemical calculations, refinement of molecular parameters. As supplementary information we use data from mass-spectrometry, vibrational and microwave spectroscopy. The primary goal is the determination of accurate and precise structures for inorganic, organic and organometallic compounds. On the basis of this data theoretical approximations are calibrated and structures of other molecules are calculated. Accordingly, our main scientific interests are
