SpaceMol is a searchable database of molecular transitions detected in space. Each entry is searchable by parameters related to the target (e.g. name, type), transition (e.g. rest wavelength, Einstein A), measured values (e.g. flux, width), and observation (e.g. instrument, program ID, date). SpaceMol additionally provides notes on transitions that include observation IDs, irregular situations, and changes from publications. Measurements of the molecular transitions are either from publications or are performed by the SpaceMol Team.
SpaceMol is expected to include spectroscopic data from three Herschel instruments (HIFI, SPIRE, and PACS) and two SOFIA instruments (EXES and GREAT). Together these instruments span a wide wavelength range, 5-670 um, covering MIR, FIR, and sub-mm wavelengths, and resolving powers of 1e3-1e7. This is the first data drop of SpaceMol, containing data from the SOFIA/EXES, Herschel/HIFI and SPIRE instruments only. The next data drop is anticipated for Spring 2027.
