Dielectric properties of 1-cyanoadamantane C10H15CN, in its plastic phase

Abstract

Dielectric properties of 1-cyanoadamantane C10H15CN are analysed in a very wide frequency band (10-109 Hz) between 200 K and 400 K. Dynamical relaxation effects are studied in relation to the structure of the plastic phase. The temperature variations of both single and correlated molecular motions are investigated. The results we obtain for the single molecular motions agree exactly with the corresponding ones deduced from N.M.R. The experimental Kirkwood correlation g factor indicates an anti-parallel local order in all the plastic phase of cyanoadamantane
