Introduction

       Our group's research focuses on the molecular structure and dynamics of surfaces and condensed phase interfaces.  Two complementary aspects of our research program are (1) development of new surface-selective laser spectroscopy techniques and (2) application of these techniques to study molecular structure (e.g., conformation), organization (orientation, packing, self-assembly), and dynamics of molecular motions in the condensed phase.  We are interested in systems important in life sciences, material science, solar energy (photovoltaics), nano- and bio-technology.

SFG line shapes paper

A detailed treatment of the spectral line shapes in BB-SFG (broad-band sum frequency generation) spectroscopy has appeared in J. Chem. Phys. 2010; 132, 234503.  In particular, the paper deals with the effects of the time delay between the IR and visible pulses on the obtained line shape.

 

"Seedling" funding under the USC CEN (Center for Energy Nanoscience)

Thanks to Sean's and Purnim's preliminary results on SFG spectroscopy of OPV (organic photovoltaics) films, our group has been selected for funding under the USC  Center for Energy Nanoscience, an EFRC (Energy Frontiers Research Center) funded by DOE.
