Carbon–Bismuth Bonds Reveal that Relativity Blurs the Textbook Line Between Sigma and Pi Bonds

Carbon–bismuth bonds reveal that relativity blurs the textbook line between sigma and pi bonds

Brown University chemists have provided direct evidence that upends the textbook explanation of how triple chemical bonds work in heavy elements. In a study published in Science, the researchers show evidence that when atomic nuclei are sufficiently heavy, the principles described in Einstein's theory of relativity change the structure of triple bonds—blurring the lines between the two separate types of bonds involved in textbook triple bonding.

Special relativity can warp chemical bonds – now we've seen it happen

In some heavy atoms, like those of bismuth (pictured in crystalline form), electrons move at relativistic speeds savva_25/Shutterstock Albert Einstein’s theory of special relativity can reshape chemical bonds within molecules, and researchers have just seen it happen for the first time. The theory of special relativity describes how moving at speeds close to the speed of light would affect travellers’ experience of space and time. Because of thi…
