Quantum effects in the structure of liquid benzene at room temperature

Abstract

Structural differences between liquid light (protonated) benzene and heavy (deuterated) benzene at room temperature have been measured using high energy electromagnetic radiation scattering techniques. Intra- and intermolecular effects have been examined, and the main quantum contribution is shown to be intramolecular. This is in contrast to the quantum effects measured in liquid water at room temperature, which are primarily intermolecular.
