The diffusion coefficient of a Zimm chain can be easily
calculated from Eqs. (7.16) and (7.17). The result
is

D_{G} |
= | (7.19) | |

(7.20) | |||

= | (7.21) |

The diffusion coefficient now scales with

In order to calculate the intrinsic viscosity of a dilute solution of Zimm chains we
go back to Eq. (6.64):

Again we shall approximate by its equilibrium value. At the end of this section we shall show that

The solution of Eq. (7.22) with this approximation is

Eqs. (6.53), (6.57) and (7.24) then yield

(7.25) |

The intrinsic viscosity scales with

We finish this section by proving Eq. (7.23). At equilibrium we
have

The last term here can be calculated according to

Eq. (7.27), (7.29) and (7.17) yield Eq. ( 7.23).
