| Abstract: | The calculations of first-order hyperpolarizabilities of thiazole derivatives dependence on the excited optical field were performed by using finite field (FF) indo/1 method. The results show that the accepter substitute radicals are key factors on influences of hyperpolarizabilities. And the donor radicals in cooperation with thiazole ring can also effect on dispersions evidently. |
