Supplementary Material

As supplementary material are presented the definition of natural internal and inter-monomer coordinates for the citric acid dimer. Also, the calculated total energy and relative energy and dipolar moments are reported for the dimer together to an analysis of the Bond Critical Point (BCP) at different theory levels and to the observed and calculated wavenumbers (cm−1), potential energy distribution and assignments.
