Chemist shows that intermolecular interactions can attain previously unknown dimensions

Posted by in category: energy

Intermolecular interactions are the forces that pertain between molecules. In general, these interactions scarcely extend beyond the boundaries of molecules. For the most part, they are effective over distances of less than 1 nanometer (10-9 m).

The largest distances discovered to date were in energy transmissions, where almost 10 nanometers were reached. A team led by LMU chemist Heinz Langhals has now found which, to the astonishment of the scientists, extend beyond 100 .

The researchers were able to demonstrate this using the concentration-dependent fluorescence decay time of dyes. “In this way, molecules can not only interact with their neighbors, but do so up to almost macroscopic dimensions,” says Langhals.
