Abstract
An investigation of the supersonic dispersion in acetaldehyde vapour was carried out in piezoelectric, magnetostriction and Kundt's tube interferometers over as wide a range of frequency and pressure as possible. Acetaldehyde is found to exhibit a multiple dispersion region which is independently confirmed by absorption measurements. This implies that certain intramolecular vibrations are activated independently.Keywords
