Slamming molecules opens new reaction paths

Rauschenbach group work published in Physical Review Letters and featured on the cover of Journal of the American Chemical Society. 

The work shows that molecules colliding on a surface at chemically-relevant energies (tunable in the range of 0—50 eV) experience motions that cause selective conformation changes and mechanochemical reactions. These dynamics are caused by the compression of the molecules as they encounter the surface at high speeds and come to a sudden halt.  The approach offers a general way to explore the conformation space and the mechanochemical reactions of any molecules that can be electrosprayed.

About the JACS Cover

Soft-collision of a carbohydrate molecule from the gas-phase onto a surface accesses many conformations of the molecule. Imaging these adsorbed conformers using scanning tunneling microscopy reveals the folding and the physical properties of carbohydrate oligomers at the single molecule level. 

This work is a close collaboration with the recently-appointed University of Oxford Newton-Abraham Visiting Professor and Max Planck Director Peter H. Seeberger.
