SpletJournal of Chemical Physics It is shown that previous methods for calculating the mean‐square end‐to‐end distance 〈r02〉 of polyethylene are invalid, since no account is taken of interactions between rotations around chain bonds. SpletIn the following, we use the general expression in Eq. 25 for the mean-square end-to-end distance. The mean-square end position can be easily calculated as σ 2 (R) = a 2 4. Since the Kronecker delta in r k, each contribution of (r k) i is the same, thus taking into account the correct counting factor, the mean-square end-to-end distance is
