| Abstract: | Two kinds of polynitrile molecules (polyaminobenzonile and polynitrobenzonile) are studied by femtosecond time-resolved optical Kerr effect. The signals of both the solutions and films display ultrafast response. The third order nonlinear optical susceptibilities and second order hyperpolarizabilities are derived and the increaseing trend of the second order hyperpolarizability versus polymerization-degree is discussed. |
