Analyzed the molecular structure of 4-Hydroxy-3-Methoxy Cinnamylic Acid (HMCA), and studied the second-order nonlinear optical properties. The results reveal that it has fairly strong SHG effect and good transparency. The cut-off wavelength λcut-off=420nm.Calculated its molecular second-order polarizability β, and a comparative study on its pertinent derivatives is carried out.-
