Abstract
The shape of stiff chains in dilute solution was considered. An average axial ratio was defined to describe the shape of the stiff chains and calculated using Tagami’s model for stiff chains. It was found that the average axial ratio is approximately proportional to λL in the stiff-chain region, where 1/2λ is the persistence length and L is the contour length of the chain. The limiting behavior agrees with Kuhn’s result for a random chain.
