It has been found that the properties of the lanthanide and actinide ions and their complexes vary linearly with the L‐values (the total angular momentum). Usually plots resembling a four segmented «inclined W» are obtained for the whole series, where the data are available. Although some deviation from a symmetrically «inclined W» plot occured in a few cases, the linearity is maintained within the four segments. It is suggested that in future, for correlating the properties of the lanthanide and actinide series, the L‐values rather than the atomic number (Z) or number of the f‐electrons, should be used.
