Chemical chameleon tamed: Researchers give floppy molecule a structure through solvent effects

How you get the chameleon of the molecules to settle on a particular "look" has been discovered by RUB chemists led by Professor Dominik Marx. The molecule CH5+ is normally not to be described by a single rigid structure, but is dynamically flexible. By means of computer simulations, the team from the Centre for Theoretical Chemistry showed that CH5+ takes on a particular structure once you attach hydrogen molecules. "In this way, we have taken an important step towards understanding experimental vibrational spectra in the future", says Dominik Marx. More...
