Relativistic effects on chemical properties [PDF]

open access: yesAccounts of Chemical Research, 1979
Special or anomalous chemical effects are examined in relation to periodic-table trends, and the degree to which these are relativistic effects are determined. It is noted that the degree to which these relativistic effects and the introduction of 4f electrons (the usual textbook explanation of the anomalies) affect chemical behavior are of approx ...
