In a recent experiment, researchers have used a new laser cooling technique that has helped to stop a trapped, rotating molecule dead in its track. Team of researchers from the Northwestern University during the study used a customized laser. The laser cooled down the single-charged aluminum monohydride molecules from room temperature to a temperature of minus 452 degree Fahrenheit within a fraction of seconds. This sudden drop in temperature successfully managed to stop the tumbling motion of molecules.
Experts said aluminum monohydride molecules were used during the study because they do not vibrate when interacting with a laser beam.
