Abstract

We present a partitioning scheme for the molecular third-order polarizability γ, in terms of local atomic contributions. These contributions allow a pictorial representation of γ in real space and its easy evaluation for long conjugated molecules. A good insight is obtained into the origin of the sign and value of the static γ in unsubstituted and push-pull polyenes and cyanines.
