 +  * 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.
