  • Mar. 2019: The program of the VAMDC-CDMS was updated. The Classic or ascii-CDMS was moved to this server. Links have been corrected and should work, but a detailed check is pending. The coding of special characters has been adjusted.
  • Nov. 2009: added note in the link which explains the aggregate spin number.
  • Dec. 2018: A new group was defined: ISM, molecules detected in the interstellar medium, but not in circumstellar shells of late-type stars.
  • Nov. 2018: A bug in the calculation of A values was fixed. This affected transitions with gup larger than 999.
  • Dec. 2015: new molecule group: cyclic species.
  • Apr. 2010: started to add values at 2.725 and 5 K for some species. The log values are also displayed in the partition function table.
