Infrared Absorption Spectra of Monohydric Alcohols

الملخص EN

FTIR spectra of homologous series of monohydric alcohols which belong to the class of partly ordered liquids were registered.

The molecules of monohydric alcohols containing hydroxyl group are able to form hydrogen-bonded clusters in the condensed phase.

The existence of clusters is clearly observed from the position and the contour of the stretch OH band in the vibrational spectra of liquid alcohols.

In this work, the experimentally registered FTIR spectra of liquid n-alcohols from methanol to decanol are presented as well as the same spectra of methanol, ethanol, propanol, butanol, pentanol, and hexanol in gas phase.
