Study of the influence of conformation and configuration on intramolecular hydrogen bonding in diols has been extended to 1, 4-dihydroxybutane derivatives The 3 p infrared spectra of 57 butane-1, 4-diols substituted only upon the 2-and 3-positions-acyclic, unsaturated, monocyclic, and bicyclic examples-were examined in detail. In a formal sense these 1, 4-diols resemble the 1, Z-diols studied earlier by similar techniques, the-CHzOH ...
