Proton relaxation in dielectrics

A kinetic equation is found which is written taking account of tunneling transitions for proton relaxation with a potential shape represented by a multiwell model having parabolic barriers. Study of the solution allows one to establish the proton relaxation mechanism in dielectrics and calculate the complex dielectric constant. Comparison with experiment shows acceptable agreement between calculated and experimental charts. Karaganda State University.
