The square root of the mean-square end-to-end distance of a
linear polymer chain averaged over all conformations of the chain. For a freely jointed chain consisting of
segments each of length
, it is given by:
The subscript zero is used to indicate unperturbed dimensions, as in
.
If this term is used repeatedly, and if it is not confusing, the abbreviated name '
end-to-end distance' may be used.
