摘      要：The dynamics of water within a nanopool of a reverse micelle is heavily affected by the amphiphilic *** this work,the terahertz(THz)spectra of cyclohexane/Igepal/water nonionic reverse micelle mixture are measured by THz timedomain spectroscopy and analyzed with two Debye models and complex permittivity of background with volume *** on the fitted parameters of bulk and fast water,the molar concentration of all kinds of water molecules and hydration water molecule number per Igepal molecule are *** find that slow hydration water has the highest proportion in water when the radius parameterω_(0)10,while bulk water becomes the main component whenω_(0)≥*** feature radius ratio of nonhydrated and hydrated water to total water nanopool is roughly obtained from 0.39 to 0.85 with increasingω_(0).
