Angular correlations within coiled polymer molecules

Monte Carlo techniques were used to investigate angular correlations between the principal axes of inertia and the end-to-end vector as well as the first two normal coordinates. On the average, the first normal coordinate is nearly parallel to the longest principal axis. The parallelism is less distinct in the case of the end-to-end vector and the longest principal axis. The assumption made by some authors that the second normal coordinate is coplanar with the two longest principal axes could not be confirmed.
