Last Lecture:

Last Lecture:. The root-mean-squared end-to-end distance, < R 2 > 1/2 , of a freely-jointed polymer molecule is N 1/2 a , when there are N repeat units, each of length a . The radius-of-gyration of a polymer, R g , is 1/6 of its root-mean-square end-to-end distance < R 2 > 1/2 .

Last Lecture:

Last Lecture:. The radius-of-gyration of a polymer, R g , is 1/6 of its root-mean-square end-to-end distance <R 2 > 1/2 . Excluded volume effects cause polymer molecules to swell (in a self-avoiding walk). Elastic (entropic) effects cause a polymer molecule to coil up.
