Different samples of plasma deposited amorphous hydrogenated carbon (HAC or a-C:H) are used
as analogs of carbonaceous dust in the diffuse interstellar (IS) medium. Comparison of measured
and theoretically calculated spectra suggests that IS dust grains are likely made of small aromatic
islands linked by aliphatic chains. Irradiation of the HAC deposits with 5 keV electrons shows that
the effects of cosmic rays on the aliphatic dust component, characterized by an absorption band at
3.4 um, are small and cannot explain the disappearance of this band in dense interstellar clouds.
