Abstract
IR spectra gained from laboratory investigations on analogue materials are an important tool for the interpretation of astronomical IR data and the understanding of the observed phenomena in DISM. Dust particles grown in argon/acetylene low pressure plasma are proposed for a new analog. We test the validity of proposed analog according to the criteria from the literature. We also present preliminary results of nitrogen band at 4.62 μm, which has been identified in dense cold dust.
