Our group's research addresses fundamental issues germane to a number of
interesting and relevant gaseous and condensed phase (liquid and solid)
environments. Experimental studies are combined with complementary
theoretical work in collaboration with theory groups such as that of
Anna Krylov. A bit of pencil-and-paper theory is done separately on
fundamental issues at the interface between chemistry and physics.
Recent and ongoing studies are:
- Photoionization of Ir(ppy)3 - arguably the most important organic
light emitting diode (OLED) molecule - is being examined, both
experimentally and theoretically.
- The physical basis of spins of massless and massive "particles"
have been examined, and applying gauge field theory to Born-Oppenheimer
systems is underway.
- The Cold Water Project studies numerous aspects of doped amorphous
solid water (ASW) thin films: ultraslow reactions, clathrate formation
and properties, phase explosions, morphological changes, species
segregation, phase transitions, astrophysical and astrochemical
applications, and so on. This is carried out jointly with Hanna Reisler.
- Photophysics and photochemistry in superfluid helium nanodroplets
has been examined for a number of dopants and phenomena.
- A combined experimental and theoretical study of the C2H radical
is being initiated. Do not be misled by the fact that this radical is
small. Conical intersections among the low-lying potentials leads to
complex dynamics. The goal is to unravel this benchmark system at an
unprecedented level of detail.
