Laser-Raman Scattering by the C34H68 Ring Molecule

Laser-Raman scattering by the C34H68 ring molecule has been measured and eight Raman bands have been observed in the region below 600 cm−1. The assignments of these bands are discussed by both the Free-Segment Model and the normal-vibration calculation. It has been shown that the observed bands may be explained as arising from either the longitudinal acoustic vibrations of the long segment consisting of 15 methylene units, or the vibrations of the fold portion. Overall molecular vibrations are also discussed.
