Summary
It is a long-held dream of physical chemists to explore and ultimately control interactions between individual molecules and atoms at the full quantum level. Crossed-molecular-beam methods combined with recent technology allow for highly-detailed experimental studies of molecular collisions. Yet, achieving fully-controlled reactive collision experiments with predetermined outcomes still remains an immense challenge, requiring control and detection of all relevant reactant and product parameters. Our world-unique crossed-beam setup combining Zeeman deceleration and velocity map imaging would enable us to finally tackle this challenge, when combined with recent cutting-edge technologies. This setup has been used successfully to perform high-resolution inelastic collision studies, and we recently started investigating reactive scattering.
Here, I propose to perform the first fully-controlled reaction experiment with predetermined outcomes. To this end, I will upgrade our setup to reach collision energies as low as 6 mK, implement laser alignment for manipulating reactant orientations, and employ 3D imaging for detecting product orientations.
To achieve this aim, we will first explore resonances and nonstatistical effects in the prototypical S + H2 → SH + H insertion reaction to demonstrate our ability to reach low energies. Simultaneously, we will laser align H2 molecules and employ 3D imaging in a separate setup to decipher molecular orientation (stereodynamical) effects in collisions involving H2. Eventually, all techniques will be merged for a fully-controlled S + H2 reaction experiment, enabling us to dictate the reaction outcome.
IQ-SCORES promises profound insight into the reaction (stereo)dynamics at the full quantum level and the long-desired power to dictate reaction outcomes with exceptional precision, thus providing an ultrasensitive test for theory. This pioneering and groundbreaking research will thereby truly revolutionize molecular reaction dynamics.
