First photographed the formation of atomic bonds in a molecule

carbon-containing molecule

For the first time scientists were able to take a picture of a molecule with a resolution of one atom in the process of covalent bond. The resulting images have a striking resemblance to the schemes that we know of chemistry textbooks.

Until now, scientists have only guessed about the molecular structures. See the individual atomic bonds length of a few tens of millionths of a millimeter each, which connect the molecule of 26 carbon atoms and 14 hydrogen atoms, it was possible using an atomic force microscope. The study was published May 30 in the online version of the journal Science.

The discovery was made by accident. Initially, the research team from the National Laboratory of the Lawrence Berkeley Department of Energy was going to create graphene nanostructures. To their surprise, during the validation of the atomic arrangement of carbon atoms microscope and photographed the chemical bonds between them.

“We did not even think that they can be so beautiful. To see what is happening on-atom level, we needed a super-sensitive atomic force microscope. No one has ever been able to photograph a single bond of individual molecules, immediately before and after the complex organic reactions, “- says Felix Fischer, who took part in the study.
