Abstract
Infrared spectra of hydrogen-bonded methyl salicylate have been studied in the temperature range 173–293 K, in solutions of various concentrations (in CCl4) and in the gaseous state. Results show that the molecules form monomerie intramolecular hydrogen bonds in the solid, liquid, and gaseous state. Far-infrared spectra were recorded which give the wavenumber of low-frequency O … O mode used in theoretical reconstruction of the band connected with the O—H stretching vibration. The position and especially the width of this band are determined to a large extent by the influence of the environment.Keywords
