Abstract
The inelastic neutron scattering spectra of the polycrystalline n-alkanes, 5<n7. At about n=21 it reaches the value found for PE, 525 cm−1. This variation in frequency with chain length for the same nominal value of κ and also the full set of calculated DFT LAM results is compared with the expectations of a simple zig–zag bead bending model.Keywords
