Research Title:
Proton Transfer Mechanisms Probed by Ultrafast Continuum mid-IR Spectroscopy

Abstract:

Using ultrafast-continuum mid-IR spectroscopy we will investigate proton transfer mechanisms both across molecular interfaces and in continuous hydrogen-bonded systems. Our new method will be able to simultaneously capture the disappearance of the initial OH/NH bonds, track the very broad spectral changes as the proton is being transferred, and measure the appearance of the new OH/NH bonds being formed in the proton transfer reaction. Being able to directly track the location of the proton through the vibrations of the bonds that are breaking and forming during the proton transfer reaction will give direct insight into the different mechanisms of proton transfer and this be able to resolve the outstanding controversies.
