  • 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.

Archive "Catalog Search Form"

  • Dec. 2018: A new group was defined: ISM, molecules detected in the interstellar medium, but not in circumstellar shells of late-type stars.
