Diffuse functions were added based on DZP set in ADF, which was called DZP+df set. The first hyperpolarizability calculations of five selected molecules show that the calculated results by using DZP+df set are much better than those by DZP set. Diffuse functions in the basis set were found to be important to calculate molecular hyperpolarizability.

Key words: nonlinear optical polarizability, DFT calculation, diffuse function
