How the hydrogen bond in NH$_4$F is revealed with Compton scattering

Materials Science 2009-04-21 v1

Abstract

In order to probe electron wave functions involved in the bonding of NH4_4F, we have performed Compton scattering experiments in an oriented single crystal and in a powder. Ab initio calculations of the Compton profiles for NH4_4F and NH4_4Cl are used to enlighten the nature of the bonds in the NH4_4F crystal. As a consequence, we are able to show significant charge transfer in the ammonium ion which is not observable using other methods. Our study provides a compelling proof for hydrogen bond formation in NH4_4F.
