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:
- <r2> = 6 <s2>
