Abstract

We present the results of electroabsorption measurements of emeraldine
base and a related phenyl capped tetramer, both spun from NMP. A
comparison of the data of the two materials shows many similarities,
indicating that the electronic structures are similar. Kramers-Kronig
analysis has been used to calculate the third order non-linear
susceptibility chi((3))(-omega;omega,0,0) as a function of energy. The
values of chi((3)) are at a maximum around 1.6 eV with values of the
order 3 x 10(-11) esu.
