Dielectric Properties of a Once-Broken Rod Polypeptide

Abstract

The theoretical interpretation of the dipole moment and the relaxation time measured experimentally on the once-broken poly(r-benzyl L-glutamate) molecule is presented in this paper. The rotatory motion of molecule can be separated by using the center-of-mass coordinates and the appropriate variables. The diffusion equation is solved by a perturbation method, and the relaxation time thus obtained can explain the experimental results.

Steady‐state and transient electric birefringence of solutions of bent‐rod macromolecules

“…The expression for model B is obtained as described above. (17) Situations may arise in which the hinge is not placed at a fixed position in all the macromolecules comprising the sample, but is located more or less randomly along the rod. For a uniform distribution, the pertinent average is so that we obtain and The results for ( Ksp)f, ( Ksp)ft, (&,)f,, and ( Ksp)fty are identical for both models.…”

“…In Eqs. (15), (17), (19), and (20), these results have been normalized to K$*, since, as stated previously, it is the value we always take for reference. In Fig.…”
