Chemical and radiative transfer modeling of Propylene Oxide
  The recent identification of the first complex chiral molecule, propylene
oxide (PrO) in space opens up a new window to further study the origin of
homochirality on the Earth. There are some recent studies to explain the
formation of PrO however additional studies on the formation of this species
are needed for better understanding. We seek to prepare a complete reaction
network to study the formation of propylene oxide in the astrophysically
relevant conditions. Based on our results, a detailed radiative transfer
modeling has been carried out to propose some more transitions which would
potentially be targeted in the millimeter wave domain. Gas-grain chemical
network was used to explain the observed abundance of PrO in a cold shell
surrounding the high-mass star-forming region of Sgr B2. Quantum chemical
calculations were employed to study various reaction parameters and to compute
multiple vibrational frequencies of PrO. To model the formation of PrO in the
observed region, we considered a dark cloud model. Additionally, we used a
model to check the feasibility of forming PrO in the hot core region. Some
potential transitions in the millimeter wave domain are predicted which could
be useful for the future astronomical detection. Radiative transfer modeling
has been utilized to extract the physical condition which might be useful to
know the properties of the source in detail. Moreover, vibrational transitions
of PrO has been provided which could be very useful for the future detection of
PrO by the upcoming James Webb Space Telescope (JWST).
