Infrared Spectra and Chemical Abundance of Methyl Propionate in Icy
  Astrochemical Conditions
  We carried out an experiment in order to obtain the InfraRed (IR) spectra of
methyl propionate (CH3CH2COOCH3) in astrochemical conditions and present the IR
spectra for future identification of this molecule in the InterStellar Medium
(ISM). The experimental IR spectrum is compared with the theoretical spectrum
and an attempt was made to assign the observed peak positions to their
corresponding molecular vibrations in condensed phase. Moreover, our
calculations suggest that methyl propionate must be synthesized efficiently
within the complex chemical network of the ISM and therefore be present in cold
dust grains, awaiting identification.
