| Abstract: | The third-order nonlinearity of five stable organic radical species with nitronyl nitroxide group was investigated using a femtosecond optical Kerr gate method. The magnitudes of their second hyperpolarizability were measured at around 10- 34 -10-32 esu. The influence of the subtle chemical change of the molecular structure was explored. The experimental results were compared with theoretical calculation. |
