Einstein's relativity rules chemical bonds in heavy elements, new research shows

Brown University chemists have discovered that Einstein's theory of relativity alters the structure of triple chemical bonds in heavy elements. This finding challenges traditional textbook models of chemical bonding by showing that relativistic effects blur the distinction between sigma and pi bonds.
Why it matters
This research fundamentally updates our understanding of atomic-level chemistry, proving that standard models fail when applied to heavy elements.
PROVIDENCE, R.I. [Brown University] — Brown University chemists have provided direct evidence that upends the textbook explanation of how triple chemical bonds work in heavy elements.
