IR Manifestation of Non-Covalent Interaction in Organic Liquids

Abstract

In this paper the IR manifestation of non-covalent interactions in benzene, methyl iodide and acetonitrile is considered. It was shown that the molecules of the mentioned compounds can form cluster shapes not only in condensed state, but also in gas phase. These structures appear due to the hydrogen bond or owing to the interaction between negatively charged atom (iodine atom) or fragment (CN-group) with a carbon atom of a neighboring molecule. As a result, the molecular chains arise, leading to the high stability of condensed state along with the dipole-dipole interaction.
