DESCRIPTION:Nonlinear optical (NLO) materials\, such as frequency doubling
  and sum harmonic generation materials\, have proved terrifically useful. 
  However\, we do not yet understand how they work or how to design better 
 ones.  We are using single crystal x-ray diffraction to generate accurate 
 electron density maps of organic NLO materials in order to explain their s
 trange behavior.  My work compares the traditional method of generating th
 e electron density to a new method: fitting a full ab initio wavefunction 
 to experimental data.
