Brownian simulations of rods with variable diameter d show that the rotational friction constant βᵣₒₜ is the same in the limit d→0 as for a probe rod in a system in which vicinal rods interact with the probe but not with each other. This agreement seems to rule out cage models. A model based on the rapid dissipation of cage forces accounts for the observed dependence of βᵣₒₜ on concentration c, length L, and d.
