Abstract
The complex dielectric permittivity of trans‐1,2‐dichlorocyclohexane (DCCH) in supercooled o‐terphenyl at audio frequencies is reported. These data are interpreted in terms of a dynamical model involving internal site exchange coupled to a cooperative solvent controlled molecular reorientation process. Fourier transform 13C lines shapes are reported for DCCH in mixed carbon tetrachloride–deuterochloroform solvent over a range of temperatures encompassing the coalescence region. Details of the site dynamics are extracted from these data via numerical line shape analysis. Reasonable agreement between the parameters common to both models is found.Keywords
