Neutrons from FRM II expose crystal structure of carbonic acid. Dr. Michael Hofmann adjusts a sample on the STRESS-SPEC neutron diffractometer. With the help of the sensitive measuring instrument, the researchers were also able to detect the crystal structure of carbonic acid. The existence of carbonic acid has long been the subject of debate: theoretically real, but practically impossible to detect. That is because the compound decomposes at the Earth's surface. A German-Chinese team of researchers working at the FRM II Research Neutron Source at the Technical University of Munich (TUM) has now made the crystalline structure of carbonic acid molecules visible for the first time. Everyone believes that they know it, but it has remained one of the biggest secrets in chemistry: carbonic acid.
