Artykuł
Infrared and near-infrared spectra of all butanols were recorded in dilute CCl4 solutions as a function of temperature. The stability of the trans and gauche conformers was evaluated from the temperature dependence of the relative band intensities. The spectra reflect various conformations of the free OH group, whereas the influence of C–C rotations on νOH and 2νOH bands was not observed. The position of these bands determines the type of conformer resulting from immediate environment of OH group, whereas the relative population of particular conformers strongly depends on steric effects of the groups in α- and β-position.
