At energies equivalent to temperatures of several thousand Kelvin fragmentation is unexpectedly precise

Selective Bond Breaking with Splat Chemistry February 1, 2021• Physics 14, 13 Colliding a large organic molecule with a surface can break a specific chemical bond in the molecule with surprising precision. L. Krumbein Figure 1: A Reichardt’s dye molecule colliding at hyperthermal velocity with a copper surface. The molecule’s orientation determines whether the energy of the collision is concentrated in one of the bonds between the central nitrogen atom (green) and a carbon atom in one of the surrounding rings (black).A Reichardt’s dye molecule colliding at hyperthermal veloc...
