The Hachmann study suggests the viability of extrapolating polymer polarizabilities from oligomers for non-conjugated species, but notes that this proves untenable for species with conjugated backbones due to electron correlation e↵ects in the ⇡-system. 12 Wong and coworkers performed a polarizability benchmark on oligomers of polydiacetylene and polybutatriene which included some hexamer polarizabilities greater than 200 Å3 . It is worth noting that despite augmented basis sets being recommended for accurate polarizability calculations, the basis sets used in this study were not augmented due resource constraints. In another benchmark study from Wong, linear polarizabilities (and hyperpolarizabilities) were found for a range of streptocyanine oligomers. By using CCSD(T)-F12 which enhances basis set convergence, they were able to give a basis set extrapolation of computed polarizabilities from a non-augmented triple zeta basis set. Both studies provide useful data, including the e↵ects of short-range exchange on polarizability and CCSD(T) calculations in the former and an assessment of MP2 quality and the importance of potential lower-energy open-shell states in the latter, however the scope of neither study was intended to examine resource e cient polarizability methods for large oligomers. With the realm of computationally-generated novel materials continuing to grow, data is needed on resource-e cient methods and basis sets to find accurate polarizabilities of largely polarizable molecules.
