First images of chemical bond differences captured

Lisa Grossman wrote:Sharing more leads to tighter bonds – even in the world of molecules. The most detailed images yet made of the chemical bonds in a molecule vividly show what large-scale models had long assumed: the more electrons two atoms share, the shorter the bond. Bonds that are more electron-dense also appear brighter in the new images.

I didn't think bond lengths were assumed, I thought they were inferred from experiment - x-ray crystallography etc.

True, but MoS is simply quoting the journalist who wrote the original. If you want to complain to New Scientist about sloppy journalism, feel free. :)
