===== General Section and General Remarks ===== | ===== General Section and General Remarks ===== |

| * Nov. 2023: The information on the meaning of lower case characters as quantum numbers was misleading and has been rephrased. The term //g//<sub>I</sub> was missing in several "useful equations" because it was assumed to be 1 initially. |
* 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. | * Mar. 2019: The program of the VAMDC-CDMS was updated. The Classic or ascii-CDMS was moved to this server.

* Dec. 2018: A new group was defined: ISM, molecules detected in the interstellar medium, but not in circumstellar shells of late-type stars. | [[archive#catalog_search_form|Archive "Catalog Search Form"]] |
* Nov. 2018: A bug in the calculation of A values was fixed. This affected transitions with //g//<sub>up</sub> larger than 999. | |
* Dec. 2015: new molecule group: cyclic species. | * Nov. 2021: A new group was defined: Other hydrocarbons, that are hydrocarbons different from the carbon chain species C<sub>n</sub>H and C<sub>n</sub>H<sub>2</sub>, but including isotopologs. |
