?Develop an expression for the fundamental vibrational frequency of a one-dimensional

Chapter 14, Problem P14D.8

(choose chapter or problem)

Develop an expression for the fundamental vibrational frequency of a one-dimensional random coil that has been slightly stretched and then released. Evaluate this frequency for a sample of polyethene of molar mass \(65 \mathrm{~kg} \mathrm{~mol}^{-1}\) at \(20^{\circ} \mathrm{C}\). Account physically for the dependence of frequency on temperature and molar mass.
