摘要：

Complex permittivities (epsilon*) for microwave radiation between 0.5 and 26 GHz have been determined for alpha-, beta-, and gamma-cyclodextrins in the solid state at room temperature. For the real component of epsilon*, maxima occur near 0.6 GHz, and the relation beta > alpha > gamma is evident across the full-frequency spectrum. Dielectric loss is significant only between 5 and 12 GHz for beta- and gamma-cyclodextrins with maxima near 7.5 GHz. (C) 2000 Elsevier Science Ltd. All fights reserved.
