| 摘 要： | 1引言分子二阶极化率是对倍频材料进行分子设计和优化筛选的重要参量，因而对它的测量也是十分重要的．用直接测量的“电场诱导二次谐波产生（EFISH）”法需要昂贵的设备，在普通实验室难以普及．近年来人们推出了简便易行的溶致变色法测定分子二阶极化率，可得出与EFISH法相平行的结果．本文采用这种方法测定了BMC（4-溴-4’-甲氧基查耳酮）和MMONS（3-甲基-4-甲氧基-4’-硝基二苯乙烯）的分子二阶极化率，并根据有关晶体二阶非线性光学数据和CNDO／S-CI方法结合微扰理论分别计算了它们的β值，得出了与溶致变色法基本一致的结果…

| Abstract: | Second-order polarizabilities of BMC and MMONS were determined by solvatocbromic method. The second-order polarizabilities of BMC and MMONS were also calculated by quantum chemical semiempirical CNDO/S-CI method and perturbation theory and second-order nonlinear optical data respectively. Calculated values are in good agreement with experimental results. The effect of molecular and crystal structure on second-order polarizabilities has also been discussed. |
