Vibrational Spectra and Potential Functions of Cyclooctane and Some Related Oxocanes

Article abstract of DOI:10.1021/j150617a014

The infrared, far-infrared, and Raman spectra of cyclooctane and two oxygenated heterocycles are examined, giving special attention to the low-frequency region.Low-frequency ring-bending vibrations are calculated from the potential outlined in the preceeding paper.The frequencies so calculated are consistent only with boat-chair structures for all three molecules.A complete normal coordinate analysis is performed on all three molecules using known force fields.
