DESCRIPTION:Title: Can we really measure circular dichroism with circular d
 ichroism spectrometers? Problems and solutions.\n\n\nAbstract: Chiroptical
  activity in inorganic nanoscale systems is a growing research area with a
 pplications ranging from catalysis and sensing to display technologies and
  quantum computation. State-of-the-art\, chiroptical materials with strong
  linear anisotropies\, however\, are difficult to accurately characterize 
 with circular dichroism (CD) because of artifactual contributions to their
  spectra from linear dichroism and birefringence. In the first portion of 
 my talk\, I will introduce CD\, the Stokes-Mueller formalism used to descr
 ibe it\, and where it reaches its limits. The second portion of my talk wi
 ll focus on the Robinson group's recent studies of CdS magic-sized cluster
 s assembled into hierarchical films with strong chiroptic responses. I'll 
 transition to Mueller matrix polarimetry\, which entirely characterizes a 
 material's response to polarized light\, and what it has revealed about th
 e films that CD could not\, concluding on the record-breaking chiroptical 
 response we recently measured.
