✦ Synopsis

A theoretical expression for the ellipticity of nn exciton band in an oriented rigid polymer is derived by use of the Frenkel exciton model in conjunction with a fully retarded expression for the partial ellipticity of an electronic transition.

Lipoxygenases convert polyunsaturated fatty acids into a number of chiral hydroperoxides, which are involved in different biological pathways. We applied the exciton-coupled circular dichroism (ECCD) method to determine the absolute configuration of acyclic hydroxylated dienes derived from the lipox
