Scientists Observe Spooky Quantum Tunneling of Ammonia

Researchers at the MIT and the Seoul National University explored quantum tunneling, a phenomenon often used in undergraduate chemistry courses to demonstrate one of the “spookinesses” of quantum mechanics. Their experimental approach is unique, and it has enormous ramifications for future efforts to interrogate molecular structure and dynamics, with the present application affording fundamental insights into the nature of tunneling-mediated phenomena.
