chain stiffness

https://doi.org/10.1351/goldbook.12209
Parameter describing the end-to-end distance of a linear, single-strand macromolecular chain having unperturbed dimensions relative to that of a model macromolecular chain not subject to short-range interactions.
Note: The steric factor, \(\sigma\), Kuhn segment length, \(l^{\prime}\), and persistence length, \(a\), are all measures of chain stiffness.
