Rotational dynamics in anisotropic confinement

摘要

Quasi-elastic nuclear resonant forward scattering experiments of the model glass former DBP:FC (Dibutylphthalate:Ferrocene) have been performed in anisotropic confinement, yielding complex spectra. A model for the rotational relaxation of Ferrocene based upon the Kubo-Anderson process is presented, which explains the observed spectra as superposition of three components: Static Ferrocene, anisotropic rotating Ferrocene and isotropic rotating Ferrocene.
