The American Chemical Society (ACS), through its Division of History of Chemistry, has an award that acknowledges these greatest of strides: the Chemical Breakthrough Awards are presented annually in recognition of “seminal chemistry publications, books, and patents that have been revolutionary in concept, broad in scope, and long-term in impact.” These awards are made to the department where the breakthrough occurred, not to the individual scientists or inventors.

This year, the ACS honored the discovery of “J-coupling” (also known as spin-spin coupling) in liquids, a breakthrough that enabled scientists to use Nuclear Magnetic Resonance (NMR) spectroscopy to identify atoms that are joined by a chemical bond and so to determine the structure of molecules.
