Imaginea unei molecule cu legaturile ei atomice

Look closely: the bonds at centre are shorter than those at the edges, as they involve more electrons A pioneering team from IBM in Zurich has published single-molecule images so detailed that the type of atomic bonds between their atoms can be discerned. It is difficult to overstate what precision measurements these are. The experiments must be isolated from any kind of vibration coming from within the laboratory or even its surroundings. They are carried out at a scale so small that room temperature induces wigglings of the AFM's constituent molecules that would blur the images, so the apparatus is kept at a cool -268C.
