%X In this paper, using the classical theoretical method, we derived the hyperpolarizabilities of chiral molecules applied to the two-coupled-oscillator model and gave the expressions of hyperpolarizabilities with microscopic parameters. We discussed the influence of microscopic parameters on the efficiency of sum-frequency generation through the relationship of hyperpolarizabilities and susceptibilities. The theoretical results obtained from the model are consistent with the known experimental facts.
