Based on the previously developed molecular theory, we 
analyze experiments in which a small periodic deformation is applied 
to a statically extended elastomer and then the dynamic modulus is 
measured as a function of the static extension ratio . The dependence 
of the loss modulus on , which 
contains three parameters, is investigated, and what information on 
the network structure is contained in these parameters is elucidated. 
The accuracy of the information obtained is discussed with the use 
of the literature experimental data.
