The unit sphere representation of hyperpolarizability tensor proposed by Tuer et al. can visually and comprehensively display anisotropic property of molecular (hyper)polarizability . We calculated the unit sphere representation of the (hyper)polarizability tensor of the four linear carbon chains and presented them in Fig. The above analysis is completely consistent with the numerical trend of the molecular (hyper)polarizability components/tensors in Figs. and.
