本文中我們對分子的一階非線性光學活性(hyperpolarizability,以β表示)及二階非線性光學活性(second hyperpolarizability,以γ表示)的理論及計算方面的發展近況做一綜合性的介紹。
A brief review of recent studies of molecular nonlinear optic using electronic structural theory is given. Developments in both methodology and models are outlined with emphasis particularly placed on structure-optical-property-relationship.
