Abstract:
Despite the fact that many sulfur-bearing molecules, ranging from
simple diatomic species up to astronomical complex molecules, have
been detected in the interstellar medium, the sulfur chemistry in
space is largely unknown and a depletion in the abundance of
S-containing species has been observed in the cold, dense interstellar
medium. The chemical form of the missing sulfur has yet to be
identified.
For these reasons, in view of the fact that there is a large abundance
of triatomic species harbouring sulfur, oxygen, and hydrogen, we
decided to investigate the HSO radical in the laboratory to try its
astronomical detection.
High-resolution measurements of the rotational spectrum of the HSO
radical were carried out within a frequency range well up into the THz
region. Subsequently, a rigorous search for HSO in the two most
studied high-mass star-forming regions, Orion KL and Sagittarius (Sgr)
B2, and in the cold dark cloud Barnard 1 (B1-b) was performed.
