Description
'Ammonia, NH3, is a tetrahedral molecule in which a nitrogen atom is displaced from a plane defined by three hydrogen atoms. In 1932, David Dennison and George Uhlenbeck at the University of Michigan made the first quantitative prediction of tunneling phenomena, that the nitrogen atom would tunnel back and forth through the barrier at a rate of 23 GHz.
This bronze and steel sculpture at the University of Michigan depicts the incipient passage of the nitrogen through the barrier presented by the plane of the hydrogen atoms.'
