| Research Abstract |
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.
