AbstractThe presence of conformers and corresponding OH rotamers in benzylalcohol and nine related compounds, dissolved in CCl4 and CS2, was studied by means of the i.r. OH stretching band. It is demonstrated that in the benzyalcohols at least two conformers are present differing in the position of the CO bond with regard to the plane of the ring, viz. at torsion angles ω of 0° and approximately 60°. The existence of a third conformation with ω = 90° cannot be excluded. The presence of different OH rotamers appears to be affected by the strength of the OH … π interaction. Effects on the distribution of conformers could not be proved.
