It has been a month since I moved to New Haven to start a postdoc at Yale. Research is going well, I am going to work on a completely new topic, the scattering of vibrationally excited molecules on metal surfaces. It’s a pretty complicated problem and I think it is going to be fun to work on it. Right now I am working on some experiments done by the Wodtke group. They essentially scatter vibrationally excited NO on a gold surface, Au(111) (see picture). One of the most interesting aspect of these experiments is that the NO can transfer the energy of 5-7 vibrational levels to excite and eject one electron from the surface. This in a bit counter intuitive since one would expect NO to transfer vibrational energy one quantum at a time and excite several electrons (think of the photoelectric effect). I hope to help solve this puzzle.
