Abstract
Following tentative detection of cyclopropene (C3H4) in Sgr B2
through its transition 3
, several attempts to confirm the
presence of cyclopropene in astronomical objects (including Sgr B2
itself) have been made. We suggest that cyclopropene may be observed in
astronomical objects through its transition 2
at 3.67218 GHz,
in absorption, even against the cosmic 2.7 K background, in a region having low
density and low kinetic temperature.
