is the end-to-end vector of the polymer.

In the physical chemistry study of polymers, the end-to-end vector is the vector that points from one end of a polymer to the other end.

The norm of the end-to-end vector is called the end-to-end distance.

The quadratic mean of the end-to-end distance <r2> can be related to the quadratic mean of the radius of gyration <s2> of a polymer by the relation:[1]

<r2> = 6 <s2>
