Theoretical Research

 

  


We're a research team based at the University of California, Irvine and our focus is to probe a new type of chemistry that occurs in the atmosphere at the interface between air and water. 

Our theoretical approaches to research include:

  • Ab initio quantum chemical calculations
  • Molecular dynamics simulations
  • Theoretical treatments of capillary waves on liquid surfaces

We use these theoretical approaches to interpret the experimental data at the most fundamental level.  For example, the graphic below shows the top view of an MD simulation of NaCl dissolved in water.  Note the ready availability of chloride ions (the yellow-green balls) at the air-water interface.  It is this availability of chloride at the interface that allows it to participate in unusual surface reactions.

 

Top view of slab of liquid water molecules (red and white balls) containing dissolved NaCl.  The small green balls are Na+, which are buried in the bulk away from the interface while the yellow-green balls are Cl-, some of which is at the interface.  From E.
