Dill \& Bromberg, Problem 10.11 Consider a four-bead polymer in two dimensions that has the microstates available to it shown in the Figure. The excited microstates have energy 0>0. The distance between the chain ends is 1 lattice unit in the compact (ground) state, 3 lattice units in the extended conformation, and 5 lattice units in each of the other conformations. Plot the average end-to-end distance as a function of temperature if the energy is (a) 0=1kcalmol1. (b) 0=3kcalmol1
