建立了一套微波辐射条件下皮秒级荧光寿命测量的实验装置。利用该装置研究了微波辐射对探针分子C153转动运动的影响。通过测量旋转速率常数的温度依赖性来确定旋转运动的活化能。与常规加热条件下测得的活化能相比,微波辐射条件下的活化能有所降低。因此,可以得出结论,在微波辐射条件下,偶极分子可以很容易地旋转。
英文摘要
An experimental apparatus that can measure fluorescence lifetime with picoseond time-resolution under microwave irradiation conditions was build up. Using the apparatus the effect of microwave irradiation on the rotational motion of a probe molecule C153 was investigated. The activation energy for the rotational motion was determined by measuring the temperature dependence of the rotational rate constants. It is found that the activation energy was reduced under the microwave irradiation conditions by comparing with that measured under conventional heating conditions. Therefore it may be concluded that, under the microwave irradiation conditions, the dipole molecule can rotate easily.
