“…[49][50][51] The detailed analysis exhibits a strong influence of the rotational motion on the time dependence of the FCS correlation function for a certain range of polymer lengths. Since actin filaments or fd viruses are within that length scale, FCS provides the opportunity to measure their rotational diffusion coefficient.…”

“…͑8͔͒ leads to much simpler normal mode amplitude correlation functions than those obtained by Aragón. [49][50][51] In particular, the various modes form an orthogonal set. The reason is the more adequate treatment of the first mode, which is artificially introduced in the weakly bending rod model.…”

“…This rigid constraint of a locally inextensible contour is the source of the difficulty in modeling the dynamics of (intrinsically) semiflexible polymers. It renders awkward any general theory [11,13,14] which tries to represent this property faithfully. On the other hand, models that relax the constraint too much -as e.g., the so-called Harris-Hearst-Beals model [15] and its latest descendants [16][17][18][19] -include artificial stretching modes and find a Gaussian distribution for all spatial distances along the contour; i.e., the essence of semiflexibility has obviously been lost.…”

“…However, as was pointed out by many workers in the field (see, e.g., Refs. [14,21]), it is conceptually important to be aware of the local anisotropy of the bending undulations caused by the rigid constraint of constant contour length.…”
