The intermolecular hydrogen–hydrogen structure of chain–molecule liquids from neutron diffraction

Abstract
Neutron diffraction isotopic substitution experiments on liquid n‐decane (C10H22) and n‐eicosane (C20H42) are described. The intermolecular H–H structure function hHH(Q) and the intermolecular H–H correlation function ginterHH(r) are obtained without recourse to models of the intramolecular structure. The structure of the ginterHH(r) found at 2.5, 5.0, and 7.0 Å corresponds to different shells in the H–H pair correlation function. In addition, ginterHH(r)13H28.
