TLDR
In this paper, the authors proposed the new polymeric systems with polar side chains which are expected to utilize both the through-bond and through-space interactions, and employed the coupled-Hartree-Fock (CHF) method to calculate the third-order hyperpolarizabilities for these systems.About:

Theoretical Studies for Third-Order Hyperpolarizabilities of Alternant and Condensed-Ring Conjugated Systems I
TL;DR: In this article, the dependences of basis sets and electron correlation effects on the third-order hyperpolarizabilities of allyl systems were examined, and it was found that the extended basis set with diffuse p and d functions and Moller-Plesset second-order perturbation (MP2) method are necessary for reasonable descriptions of at least relative tendencies for these charged states of the allyl system.
