Abstract
Complex permittivities (epsilon*) for microwave radiation between 0.5 and 2 6 GHz have been determined for alpha-, beta-, and gamma-cyclodextrins in th e solid state at room temperature. For the real component of epsilon*, maxi ma occur near 0.6 GHz, and the relation beta > alpha > gamma is evident acr oss the full-frequency spectrum. Dielectric loss is significant only betwee n 5 and 12 GHz for beta- and gamma-cyclodextrins with maxima near 7.5 GHz. (C) 2000 Elsevier Science Ltd. All fights reserved.
