Molecular acoustics. Part 4.—Volume change between conformational isomers

open access: closedTrans. Faraday Soc., 1970
By comparing ultrasonic with n.m.r. and equilibration data on conformational equilibria it has been shown that the conformers present in each of the substances 1,1,2-tribromoethane, meso-2,3-dibromobutane and 4-methyl-1,3-dioxan differ in volume by 1–3 %. This result is also consistent with density data on some cyclic compounds.
