How molecules move energy after light absorption

Molecule 111222152010-large

MSU chemist Jim McCusker and postdoctoral researcher Dong Guo proved an 84-year-old theory.

The same principle that causes figure skaters to spin faster as they draw their arms into their bodies has now been used by Michigan State University researchers to understand how molecules move energy around following the absorption of light.

Conservation of angular momentum is a fundamental property of nature, one that astronomers use to detect the presence of satellites circling distant planets. In 1927, it was proposed that this principle should apply to chemical reactions, but a clear demonstration has never been achieved…
