Recent Scientific Results

(1a)    Theory for evaluating the effect of electron spin on Jahn-Teller distortions in
          mixed-valence clusters which explains spin states and valence delocalization
          patterns in bi-, tri-, and tetranuclear clusters.

(1b)    Predictions concerning the influence of spin and valence class on the rate of
          long-range electron transfer involving clusters that await experimental test.

(1c)    Interpretation of an unusual localization-to-delocalization transition in a mutant
          ferredoxin.

(2)     Theory for molecular Magnetic Linear Dichroism (MLD), which explains all trends
          in the data obtained thus far with this newly developed technique.  These properties
          include band shape,  field and temperature dependence of the MLD effect.
