抄録

The gas-phase infrared spectra of 1,2-dimethoxyethane measured at various temperatures gave a value of 0.31 ± 0.04 kcal mol<SUP>−1</SUP> for the energy difference between the <I>trans–gauche–gauche</I>′ and <I>trans–trans–trans</I> conformers, the latter being more stable. This value is in good agreement with the results of high-level <I>ab initio</I> calculations. The present experimental finding gives definitive evidence for the importance of an intramolecular 1,5-CH···O interaction in the stabilization of the <I>trans–gauche–gauche</I>′ conformer in the gas phase.
